Procedure

The title compound was prepared using the method of Example 34(d) starting from (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (200 mg, 0.767 mmol) and imidazo[1,2-a]pyrimidine-2-carboxylic acid (163 mg, 0.997 mmol). The product was triturated with acetonitrile. Yield 168 mg (54%). 1H-NMR (400 MHz; d6-DMSO): δ 1.18 (d, 3H), 4.32-4.45 (m, 2H), 4.49-4.56 (m, 1H), 6.92 (d, 1H), 7.13-7.16 (m, 1H), 7.84 (d, 1H), 7.95 (d, 1H), 8.03-8.06 (m, 2H), 8.25 (s, 1H), 8.67-8.69 (m, 1H), 8.75 (d, 1H), 8.97-8.99 (m, 1H).
