Versuchsvorschrift
The title compound was prepared using the method of Example 34(d) starting from 2-acetylthiazole-4-carboxylic acid (1.444 g, 8.44 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (2.0 g, 7.67 mmol). The product was purified by recrystallization from ethanol. Yield 93%. 1H-NMR (400 MHz; DMSO-d6): δ 1.20 (d, 3H), 2.70 (s, 3H), 4.37 (dd, 1H), 4.44 (dd, 1H), 4.48-4.56 (m, 1H), 6.96 (d, 1H), 7.87 (d, 1H), 7.92 (dd, 1H), 7.97 (dd, 1H), 8.04 (d, 1H), 8.48 (d, 1H), 8.61 (s, 1H).
