Procedure
The title compound was prepared using the method of Example 34(d) starting from Imidazo[1,2-a]pyrimidine-2-carboxylic acid (0.076 g, 0.466 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chloro-6-fluorobenzonitrile (0.1 g, 0.359 mmol). The product was purified by recrystallization from acetonitrile. Yield 46.0%. 1H-NMR (400 MHz; CDCl3): δ 1.32 (d, 3H), 4.33 (dd, 1H), 4.44 (dd, 1H), 4.57-4.67 (m, 1H), 6.57 (dd, 1H), 6.97 (dd, 1H), 7.50 (d, 1H), 7.59 (dd, 1H), 7.71 (dd, 1H), 7.80 (d, 1H), 8.08 (s, 1H), 8.47 (dd, 1H), 8.66 (dd, 1H).
