Procedure

(S)—N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5-(hydroxymethyl)isoxazole-3-carboxamide was prepared using the method of Example 34(d) starting from (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (200 mg, 0.675 mmol) and 5-(hydroxymethyl)isoxazole-3-carboxylic acid (126 mg, 0.878 mmol). The product purified twice by Flash-chromatography (normal phase and reverse phase) and triturated using diethyl ether. Yield 1.9%. 1H-NMR (400 MHz; MeOD): δ 1.26 (d, 3H), 4.28-4-43 (m, 2H), 4.52-4.63 (m, 1H), 4.68 (d, 2H), 6.57 (t, 1H), 6.77 (d, 1H), 7.70 (d, 1H), 7.78 (dd, 1H), 7.88 (dd, 1H), 8.07 (dd, 1H).
