N-(2-(3-(3-chloro-4-cyano-2-methylphenyl)isoxazol-5-yl)ethyl)-3-(pyridin-3-yl)-1H-pyrazole-5-carboxamide was prepared from 4-(5-(2-aminoethyl)isoxazol-3-yl)-2-chloro-3-methylbenzonitrile hydrochloride (54.8 g, 0.184 mmol), 3-(pyridin-3-yl)-1H-pyrazole-5-carboxylic acid (34.8 mg, 0.184 mmol), HOBt hydrate (42.2 mg, 0.276 mmol), DIPEA (0.096 ml, 0.551 mmol) and EDCI (53 mg, 0.276 mmol) using DCM as solvent as described in previous Example. The crude product was purified by preparative HPLC to give the title compound 13 mg. 1H-NMR (400 MHz; CDCl3): δ 2.47 (s, 3H), 3.23 (t, 2H), 3.89 (m, 2H), 6.30 (s, 1H), 7.09 (bs, 1H), 7.22 (bs, 1H), 7.40 (m, 2H), 7.57 (d, 1H), 7.98 (d, 1H), 8.62 (bs, 1H), 8.95 (bs, 1H).
