Procedure

(S)-2-amino-N-(1-(3-(3-chloro-4-cyano-2-methylphenyl)-1H-pyrazol-1-yl)-propan-2-yl)oxazole-4-carboxamide was prepared using the method of Example 34(d) starting from 2-amino-1,3-oxazole-4-carboxylic acid (0.196 g, 1.527 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-3-methylbenzonitrile (0.437 g, 1.272 mmol). The product was purified by Flash-chromatography. Yield 29.0%. 1H-NMR (400 MHz; CDCl3): δ 1.23 (d, 3H), 2.58 (s, 3H), 4.29 (dd, 1H), 4.39 (dd, 1H), 4.54 (m, 1H), 4.59 (s, 2H), 6.44 (d, 1H), 7.31 (d, 1H), 7.50 (d, 1H), 7.53 (dd, 1H), 7.58 (dd, 1H), 7.68 (s, 1H).
