Reaction Steps

Following the general procedure-2, 3,5-dichloro-N-[6-(3,5-dicyclopropyl-1H-pyrazol-1-yl)pyridin-3-yl]isonicotinamide (24 mg) was prepared from 3,5-dichloroisonicotinoyl chloride (313 mg, 1.5 mmol) and intermediate 30 (200 mg, 0.75 mmol) as a white 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 (7 mg) as a pale-yellow solid. M.P.: 193-195° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 11.34 (s, 1H), 8.82 (s, 2H), 8.69 (d, J 2.4, 1H), 8.24 (dd, J 2.6, 8.9, 1H), 7.78 (d, J 8.9, 1H), 5.83 (s, 1H), 2.72-2.64 (m, 1H), 1.80-1.70 (m, 1H), 0.92-0.82 (m, 4H), 0.70-0.58 (m, 4H). MS (m/z): 413.40 [M−H−HCl]+.
