Procedure

The title compound was prepared using the method of Example 34(d) starting from 2,4,6,7-tetrahydropyrano[4,3-c]pyrazole-3-carboxylic acid (0.078 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 32.5%. 1H-NMR (400 MHz; CDCl3): δ 1.22 (d, 3H), 2.79 (t, 2H), 3.89-3.94 (m, 2H), 4.27 (dd, 1H), 4.39 (dd, 1H), 4.48-4.58 (m, 1H), 4.84-4.94 (m, 2H), 6.61 (d, 1H), 7.52 (d, 1H), 7.65 (dd, 1H), 7.69 (d, 1H), 7.80-7.82 (m, 1H).
