Procedure

The title compound was synthesized from (R)-4-(1-(1-aminopropan-2-yl)-1H-pyrazol-3-yl)-2,6-difluorobenzonitrile (0.955 g, 3.64 mmol), 5-acetylisoxazole-3-carboxylic acid (0.565 g, 3.64 mmol), HOBt (0.738 g, 5.46 mmol), DIPEA (1.9 mL, 10.92 mmol) and EDCI (1.05 g, 5.46 mmol) using DMF (10 mL) as solvent using the method of Example 34(d). The product was purified with CombiFlash to afford 60 mg of pure product. 1H NMR (400 MHz; CDCl3): δ 1.63 (d, 3H), 2.64 (s, 3H), 3.82 (m, 1H), 3.95 (m, 1H), 4.64 (m, 1H), 6.61 (d, 1H), 7.29 (s, 1H), 7.52 (m, 3H), 7.62 (m, 1H).
