Reaction Steps

The title compound was prepared using the method of Example 34(d) starting from 1H-benzo[d]imidazole-2-carboxylic acid (100 mg, 0.617 mmol) and (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (161 mg, 0.617 mmol) using N,N-dimethyl formamide as the solvent. The product was purified by flash chromatography and recrystallized from chloroform, respectively. Yield 20.03%. 1H-NMR (400 MHz; CDCl3): δ 1.33 (d, 3H), 4.32 (dd, 1H), 4.47 (dd, 1H), 4.64-4.75 (m, 1H), 6.59 (d, 1H), 7.34-7.41 (m, 2H), 7.50 (d, 1H), 7.52-7.56 (m, 1H), 7.62 (d, 1H), 7.81-7.87 (m, 2H), 8.00 (d, 1H), 8.42 (d, 1H), 10.87 (s, 1H).
