The present invention relates to novel compounds, to pharmaceutical compositions comprising the compounds, to processes for making the compounds and to the use of the compounds in therapy. More particularly, it relates to certain macrocyclic compounds which exhibit Trk family protein tyrosine kinase inhibition, and which are useful in the treatment of pain, cancer, inflammation, neurodegenerative diseases and certain infectious diseases. The current treatment regimes for pain conditions utilize several classes of compounds. The opioids (such as morphine) have several drawbacks including emetic, constipatory and negative respiratory effects, as well as the potential for addiction. Non-steroidal anti-inflammatory analgesics (NSAIDs, such as COX-1 or COX-2 types) also have drawbacks including insufficient efficacy in treating severe pain and the potential for internal gastrointestinal bleeding. In addition, COX-1 inhibitors can cause ulcers of the mucosa. Accordingly, there is a continuing need for new and more effective treatments for the relief of pain, especially chronic pain. Trk's are high affinity receptor tyrosine kinases activated by a group of soluble growth factors called neurotrophins (NT). The Trk receptor family has three members: TrkA, TrkB and TrkC. Among the neurotrophins are (i) nerve growth factor (NGF) which activates TrkA, (ii) brain-derived neurotrophic factor (BDNF) and NT-4/5 which activate TrkB and (iii) NT3 which activates TrkC. Trk's are widely expressed in neuronal tissue and are implicated in the maintenance, signaling and survival of neuronal cells (Patapoutian, A. et al., Current Opinion in Neurobiology, 2001, 11, 272-280). Inhibitors of the Trk/neurotrophin pathway have been demonstrated to be effective in numerous pre-clinical animal models of pain. For example, antagonistic NGF and TrkA antibodies such as RN-624 have been shown to be efficacious in inflammatory and neuropathic pain animal models (Woolf, C. J. et al. (1994) Neuroscience 62, 327-331; Zahn, P. K. et al. (2004) J. Pain 5, 157-163; McMahon, S. B. et al., (1995) Nat. Med. 1, 774-780; Ma, Q. P. and Woolf, C. J. (1997) Neuroreport 8, 807-810; Shelton, D. L. et al. (2005) Pain 116, 8-16; Delafoy, L. et al. (2003) Pain 105, 489-497; Lamb, K. et al. (2003) Neurogastroenterol. Motil. 15, 355-361; Jaggar, S. I. et al. (1999) Br. J. Anaesth. 83, 442-448) and neuropathic pain animal models (Ramer, M. S. and Bisby, M. A. (1999) Eur. J. Neurosci. 11, 837-846; Ro, L. S. et al. (1999); Pain 79, 265-274 Herzberg, U. et al. (1997) Neuroreport 8, 1613-1618; Theodosiou, M. et al. (1999) Pain 81, 245-255; Li, L. et al. (2003) Mol. Cell. Neurosci. 23, 232-250; Gwak, Y. S. et al. (2003) Neurosci. Lett. 336, 117-120). It has also been shown that NGF secreted by tumor cells and tumor invading macrophages directly stimulates TrkA located on peripheral pain fibers. Using various tumor models in both mice and rats, it was demonstrated that neutralizing NGF with a monoclonal antibody inhibits cancer related pain to a degree similar or superior to the highest tolerated dose of morphine. In addition, activation of the BDNF/TrkB pathway has been implicated in numerous studies as a modulator of various types of pain including inflammatory pain (Matayoshi, S., J. Physiol. 2005, 569:685-95), neuropathic pain (Thompson, S. W., Proc. Natl. Acad. Sci. USA 1999, 96:7714-18) and surgical pain (Li, C.-Q. et al., Molecular Pain, 2008, 4(28), 1-11). Recent literature has also shown that overexpression, activation, amplification and/or mutation of Trk kinases are associated with many cancers including neuroblastoma (Brodeur, G. M., Nat. Rev. Cancer 2003, 3, 203-216), ovarian (Davidson. B., et al., Clin. Cancer Res. 2003, 9, 2248-2259), colorectal cancer (Bardelli, A., Science 2003, 300, 949), melanoma (Truzzi, F., et al., Dermato - Endocrinology 2008, 3 (1), pp. 32-36), head and neck cancer (Yilmaz, T., et al., Cancer Biology and Therapy 2010, 10 (6), pp. 644-653), gastric carcinoma (Du, J. et al., World Journal of Gastroenterology 2003, 9 (7), pp. 1431-1434), lung carcinoma (Ricci A., et al., American Journal of Respiratory Cell and Molecular Biology 25 (4), pp. 439-446), breast cancer (Jin, W., et al., Carcinogenesis 2010, 31 (11), pp. 1939-1947), Glioblastoma (Wadhwa, S., et al., Journal of Biosciences 2003, 28 (2), pp. 181-188), medulloblastoma (Gruber-Olipitz, M., et al., Journal of Proteome Research 2008, 7 (5), pp. 1932-1944), secratory breast cancer (Euthus, D. M., et al., Cancer Cell 2002, 2 (5), pp. 347-348), salivary gland cancer (Li, Y.-G., et al., Chinese Journal of Cancer Prevention and Treatment 2009, 16 (6), pp. 428-430), papillary thyroid carcinoma (Greco, A., et al., Molecular and Cellular Endocrinology 2010, 321 (1), pp. 44-49) and adult myeloid leukemia (Eguchi, M., et al., Blood 1999, 93 (4), pp. 1355-1363). In preclinical models of cancer, non-selective small molecule inhibitors of Trk A, B and C were efficacious in both inhibiting tumor growth and stopping tumor metastasis (Nakagawara, A. (2001) Cancer Letters 169:107-114; Meyer, J. et al. (2007) Leukemia, 1-10; Pierottia, M. A. and Greco A., (2006) Cancer Letters 232:90-98; Eric Adriaenssens, E., et al. Cancer Res (2008) 68:(2) 346-351). In addition, inhibition of the neurotrophin/Trk pathway has been shown to be effective in treatment of pre-clinical models of inflammatory diseases with NGF antibodies or non-selective small molecule inhibitors of Trk A, B and C. For example, inhibition of the neurotrophin/Trk pathway has been implicated in preclinical models of inflammatory lung diseases including asthma (Freund-Michel, V; Frossard, N., Pharmacology & Therapeutics (2008), 117(l), 52-76), interstitial cystitis (Hu Vivian, Y., et. al. The Journal of Urology (2005), 173(3), 1016-21), inflammatory bowel diseases including ulcerative colitis and Crohn's disease (Di Mola, F. F., et. al., Gut (2000), 46(5), 670-678) and inflammatory skin diseases such as atopic dermatitis (Dou, Y.-C., et. al. Archives of Dermatological Research (2006), 298(1), 31-37), eczema and psoriasis (Raychaudhuri, S. P., et al., J. Investigative Dermatology (2004), 122(3), 812-819). The neurotrophin/Trk pathway, particularly BDNF/TrkB, has also been implicated in the etiology of neurodegenerative diseases including multiple sclerosis, Parkinson's disease and Alzheimer's Disease (Sohrabji, F., Lewis, Danielle K., Frontiers in Neuroendocrinology (2006), 27(4), 404-414). The TrkA receptor is also thought to be critical to the disease process in the infection of the parasitic infection of Trypanosoma cruzi (Chagas disease) in human hosts (de Melo-Jorge, M., et al., Cell Host & Microbe (2007), 1(4), 251-261). Several classes of small molecule inhibitors of Trk kinases said to be useful for treating pain or cancer are known ( Expert Opin. Ther. Patents (2009) 19(3)). There remains a need, however, for compounds and methods for the treatment of pain, in particular chronic pain, as well as for the treatment of cancer, inflammation, neurodegenerative diseases and certain infectious diseases. SUMMARY OF THE INVENTION It has now been found that macrocyclic compounds are inhibitors of Trk kinases, in particular inhibitors of TrkA and/or TrkB and/or TrkC, and are useful for treating disorders and diseases such as cancer and pain, including chronic and acute pain.

This type of pain generally comes on suddenly, for example, after trauma or surgery, and may be accompanied by anxiety or stress. The cause can usually be diagnosed and treated, and the pain is confined to a given period of time and severity. In some rare instances, it can become chronic. Chronic pain, as defined by the International Association for the Study of Pain, is widely believed to represent disease itself. It can be made much worse by environmental and psychological factors. Chronic pain persists over a longer period than acute pain and is resistant to most medical treatments, generally over 3 months or more. It can and often does cause severe problems for patients.

Preparation A (R)-5-fluoro-2-methoxy-3-(pyrrolidin-2-yl)pyridine Step A: Preparation of (R)-tert-butyl 2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidine-1-carboxylate A solution of tert-butyl pyrrolidine-1-carboxylate (4.09 mL, 23.4 mmol) and (−)-sparteine (6.44 mL, 28.0 mmol) in MTBE (50 mL) was cooled to −78° C. and sec-BuLi (20 mL, 28.0 mmol, 1.4M in cyclohexane) was introduced drop-wise by cannula, keeping the internal temperature under −78° C. The resulting solution was stirred for 3 hours at −78° C., followed by addition of a solution of ZnCl 2 (21.0 mL, 21.0 mmol, 1M in Et 2 O) drop-wise with rapid stirring, keeping the internal temperature below −65° C. The resulting light suspension was stirred at −78° C. for 10 minutes and then warmed to ambient temperature. The resulting mixture was sequentially charged with 3-bromo-5-fluoro-2-methoxypyridine (5.05 g, 24.5 mmol), Pd(OAc) 2 (0.262 g, 1.17 mmol) and t-Bu 3 P-HBF 4 (0.407 g, 1.40 mmol) in one portion. After stirring overnight at ambient temperature, concentrated NH 4 OH (1 mL) was added and the reaction was stirred for 1 hour. The resulting slurry was filtered through Celite® and washed with Et 2 O. The organic layer was filtered and concentrated, and the crude product was purified by silica column chromatography, eluting with 5% EtOAc/hexanes to give product (R)-tert-butyl 2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidine-1-carboxylate as yellow oil (4.34 g, 63% yield). Step B: Preparation of (R)-5-fluoro-2-methoxy-3-(pyrrolidin-2-yl)pyridine A DCM (12 mL) solution of TFA (11.3 mL, 146 mmol) was added to (R)-tert-butyl 2-(5-fluoro-2-methoxypyridin-3-yl)pyrrolidine-1-carboxylate (4.33 g, 14.6 mmol) and stirred at ambient temperature for 1 hour. The reaction was then concentrated, taken up in EtOAc, then washed with NaHCO 3 and brine. The organic phase was dried (MgSO 4 ), filtered, and concentrated, and the crude material was purified by silica column chromatography eluting with a 1-2% 7N NH 3 -MeOH/DCM to afford (R)-5-fluoro-2-methoxy-3-(pyrrolidin-2-yl)pyridine as a liquid (1.40 g, 49% yield). The enantiomeric excess (ee %) of (R)-5-fluoro-2-methoxy-3-(pyrrolidin-2-yl)pyridine was determined as follows: To a propan-2-ol solution of small amount of ((R)-5-fluoro-2-methoxy-3-(pyrrolidin-2-yl)pyridine was added excess N-(2,4-dinitro-5-fluorophenyl)-L-alanine amide (FDAA, Marfey's reagent). The mixture was heated to reflux for approximately two minutes.

The combined organic layers were dried over MgSO 4 , filtered, and concentrated under reduced pressure to give the crude material that was purified by silica column chromatography, eluting with 0-50% EtOAc/Hexanes to afford ethyl 5-(4,4-difluoro-2-(5-fluoro-2-methoxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate (0.126 g, 65.6% yield). MS (APCI) m/z=420.9 (M+H). Step E: Preparation of 5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid To a solution of ethyl 5-(4,4-difluoro-2-(5-fluoro-2-methoxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate (0.126 g, 0.267 mmol) in CH 2 Cl 2 (1.3 mL) at 0° C. was added 1M BBr 3 in CH 2 Cl 2 (1.50 mL, 1.50 mmol). The resulting mixture was warmed to ambient temperature and stirred for 18 hours. The reaction mixture was diluted with CH 2 Cl 2 (5 mL) and poured into a mixture of ice and saturated aqueous NaHCO 3 (3 mL). The aqueous layer was then acidified to about pH 3 with 1N aqueous HCl. The aqueous layer was extracted with CH 2 Cl 2 (3×10 mL). The combined organic layers were dried over MgSO 4 , filtered, and concentrated under reduced pressure to give a mixture of ethyl 5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylate and 5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid. This mixture was taken up in MeOH-THF (0.25 mL/0.75 mL) at ambient temperature, and 2N aqueous LiOH (0.667 mL, 1.33 mmol) was added. The resulting mixture was heated at 50° C. for 24 hours. The reaction mixture was cooled to ambient temperature and concentrated under reduced pressure to remove the organic solvents. The residue was diluted with 5 mL of EtOAc and acidified to pH 3 to 4 with 6N aqueous HCl with stirring. The organic layer was separated and the acidic aqueous layer was extracted with EtOAc (2×5 mL). The combined organic layers were dried over MgSO 4 , filtered, and concentrated under reduced pressure to afford 5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (0.094 g, 93.1% yield). MS (APCI) m/z=378.9 (M+H). Step F: Preparation of N—((S)-3-chloro-2-hydroxypropyl)-5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidin-3-carboxamide To a mixture of 5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxylic acid (0.047 g, 0.124 mmol) and HOBT (0.0252 g, 0.186 mmol) in DMF (1 mL) at ambient temperature was added EDCI (0.0357 g, 0.186 mmol). The resulting mixture was stirred for 1 hour. To this mixture was added (S)-1-amino-3-chloropropan-2-ol hydrochloride (Example 19, Step A; 0.0218 g, 0.149 mmol) followed by DIEA (0.0656 mL, 0.373 mmol) at ambient temperature. The resulting mixture was stirred for 48 hours. The reaction mixture was diluted with EtOAc (10 mL), and the organic layer was washed with a 1:1 mixture of brine and water. The aqueous layer was separated and extracted with EtOAc (2×10 mL). The combined organic layers were washed with a 1:1 mixture of brine and water (15 mL) and combined with the organic layer obtained previously. The organic layer was dried over MgSO 4 , filtered, and concentrated under reduced pressure to afford N—((S)-3-chloro-2-hydroxypropyl)-5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (0.061 g, 105% yield). LC/MS (ES+APCI) m/z=468.1 (M−H). Step G: Preparation of Diastereomers 1 and 2 of (15S)-4,4,9-trifluoro-15-hydroxy-13-oxa-2,17,21,22,25-pentaazapentacyclo[17.5.2.0 2,6 .0 7,12 .0 22,26 ]hexacosa-1 (25),7 (12),8,10,19(26),20,23-heptaen-18-one A mixture of N—((S)-3-chloro-2-hydroxypropyl)-5-(4,4-difluoro-2-(5-fluoro-2-hydroxyphenyl)pyrrolidin-1-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (0.060 g, 0.128 mmol) and Cs 2 CO 3 (0.208 g, 0.639 mmol) in DMF (6.4 mL) was heated at 85° C. for 30 minutes. The reaction mixture was cooled to ambient temperature and filtered. The filtrate was concentrated under reduced pressure to give the crude material which was purified by silica gel flash column chromatography (CH 2 Cl 2 to NH 4 OH:MeOH:CH 2 Cl 2 =0.5:5:95) to afford a mixture of the diastereomers. The isolated diastereomers were further purified by chiral column chromatography (Chiral Tech OD-H column, 20% EtOH in hexanes). Fractions having a retention time of about 17.1 minutes were isolated to afford the title compound designated as Diastereomer 1 (11 mg, 20% yield; MS (APCI) m/z=434.2 (M+H). Fractions having a retention time of about 21.0 minutes were isolated to provide the title compound designated as Diastereomer 2 (13 mg; 24% yield); MS (APCI) m/z=434.2 (M+H).
