Procedure
The title compound was prepared using the method of Example 34(d) starting from 5-(2-furyl)-2H-pyrazole-3-carboxylic acid (3.42 g, 19.18 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (5 g, 19.18 mmol). The product was purified by flash chromatography and recrystallization from acetonitrile, respectively. Yield 16.97%. 1H-NMR (400 MHz; CDCl3): δ 1.26 (d, 3H), 4.30 (dd, 1H), 4.42 (dd, 1H), 4.53-4.63 (m, 1H), 6.50 (dd, 1H), 6.62 (d, 1H), 6.67 (d, 1H), 6.94 (s, 1H), 7.48 (dd, 1H), 7.53 (d, 1H), 7.68 (d, 1H), 7.73-7.84 (m, 2H), 8.02 (s, 1H), 13.70 (broad s, 1H).
