Procedure

(S)—N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)oxazole-4-carboxamide was prepared using the method of Example 34(d) starting from 4-oxazolecarboxylic acid (0.212 g, 1.841 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (0.4 g, 1.534 mmol). The product was triturated using diethyl ether. Yield 32.9%. 1H-NMR (400 MHz; DMSO-d6): δ 1.11 (d, 3H), 4.31 (dd, 1H), 4.38 (dd, 1H), 4.41-4.49 (m, 1H), 6.95 (d, 1H), 7.84 (d, 1H), 7.97-8.01 (m, 2H), 8.15 (dd, 1H), 8.52 (d, 1H), 8.52 (d, 1H), 8.59 (d, 1H).
