[0242] To a microwave vial (Personal Chemistry) was added (2R)-2-[(2,5-dichloropyrimidin-4-yl)amino]-2-(4-fluorophenyl)ethanol (Method 1, 250 mg, 0.83 mmol), 5-cyclopropyl-1H-pyrazol-3-amine (204 mg, 1.66 mmol), DIPEA (0.17 mL, 0.97 mmol) and n-butanol (2 mL). The reaction mixture was heated to 160°C and maintained for 5 hours. Solvent was removed. The white solid was purified by semi-preparative HPLC (Gilson) to give the title compound (43 mg, 13%). 1 H NMR (300MHz, DMSO-d6) δ0.76(m, 2H), 0.97(m, 2H), 1.87(m, 1H), 3.73-3.85(m, 2H), 5.22(m, 2H), 7.13( m, 2H), 7.47 (m, 2H), 7.97 (d, 1H), 8.28 (s, 1H).

Abstract

The present invention relates to novel compounds of formula I, and to pharmaceutical compositions thereof and methods of use thereof. These new compounds offer a cure for cancer.

Description

field of invention [0001] The present invention relates to novel pyrazole derivatives, their pharmaceutical compositions and their methods of use. Furthermore, the present invention relates to therapeutic methods for the treatment and prevention of cancer, and to the use of these pyrazole derivatives in the manufacture of medicaments for the treatment and prevention of cancer. Background of the invention [0002] Receptor tyrosine kinases (RTK's) are a subclass of protein kinases that play an important role in cell signaling and are involved in a variety of cancer-related processes including cell proliferation, survival, angiogenesis and metastasis. Currently up to 100 different RTk'S have been identified including tropomyosin-related kinases (Trk'S). [0003] Trk'S are high affinity receptors activated by a group of lytic growth factors called neurotrophins (NT). The Trk receptor family has three members: TrkA, TrkB and TrkC. In NT, there are (i) nerve growth factor (NGF...
