Procedure

(S)-ethyl 4-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl-carbamoyl)thiazole-2-carboxylate was prepared using the method of Example 34(d) starting from 2,4-thiazoledicarboxylic acid, 2-ethyl ester (0.556 g, 2.76 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (0.6 g, 2.301 mmol). The product was triturated using diethyl ether. Yield 51.9%. 1H-NMR (400 MHz; DMSO-d6): δ 1.18 (d, 3H), 1.34 (t, 3H), 4.34 (dd, 1H), 4.39-4.46 (m, 3H), 4.47-4.55 (m, 1H), 6.94 (d, 1H), 7.83 (d, 1H), 7.94-7.96 (m, 2H), 8.02 (t, 1H), 8.55 (s, 1H), 8.60 (d, 1H).
