Reaction Steps

(R)—N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-2-(pyrrolidin-1-ylmethyl)thiazole-4-carboxamide was prepared using the method of Example 34(d) starting from 2-pyrrolidin-1-ylmethyl-thiazole-4-carboxylic acid (0.244 g, 1.151 mmol) and (R)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (0.2 g, 0.767 mmol). The crude product was washed with water. Yield 55.7%. 1H-NMR (400 MHz; DMSO-d6): δ 1.23 (d, 3H), 1.72-1.76 (m, 4H), 2.57-2.61 (m, 4H), 3.95 (s, 2H), 4.32 (dd, 1H), 4.41 (dd, 1H), 4.41-4.50 (m, 1H), 6.96 (d, 1H), 7.85 (d, 1H), 7.95 (dd, 1H), 7.98 (dd, 1H), 8.09 (dd, 1H), 8.13 (s, 1H), 8.44 (d, 1H).
