Following the general procedure-1, N-{4-[5-cyclopropyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]phenyl}-2-(pyridin-4-yl)acetamide (38 mg) was prepared from 2-(pyridin-4-yl)acetic acid (94 mg, 0.54 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 (30 mg) as a brown solid. M.P. 135-139° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 10.93 (s, 1H), 8.85 (d, J 5.8, 2H), 8.01 (d, J 5.8, 2H), 7.81 (d, J 8.6, 2H), 7.58 (d, J 8.6, 2H), 6.59 (s, 1H), 4.13 (s, 2H), 1.83-1.74 (m, 1H), 0.99-0.91 (m, 2H), 0.83-0.76 (m, 2H). MS (m/z): 387.27 [M+H−HCl]+.
