Following the general procedure-1, N-{4-[5-cyclopropyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]phenyl}-2-(pyridin-2-yl)acetamide (107 mg) was prepared from 2-pyridylacetic acid (124 mg, 0.71 mmol) and intermediate 31 (120 mg, 0.45 mmol) as a pale yellow solid and dissolved in THF. Saturated HCl in diethyl ether was added to this solution at 0° C. and stirred for 15 min Solid that separated out was filtered and dried to give the title compound (90 mg) as a pale yellow solid. M.P. 210-215° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 10.80 (s, 1H), 8.79 (d, J 4.8, 1H), 8.31 (t, J 7.2, 1H), 7.86 (d, J 7.4, 1H), 7.84-7.79 (m, 4H), 7.59 (d, J 8.8, 2H), 6.60 (s, 1H), 4.20 (s, 2H), 1.85-1.75 (m, 1H), 0.99-0.90 (m, 2H), 0.82-0.75 (m, 2H). MS (m/z): 420.89 [M−H]−.
