Reaction Steps

The title compound was prepared using the method of Example 34(d) starting from 1-methyl-1H-imidazole-4-carboxylic acid (53.0 mg, 0.420 mmol) and (S)-1-(2-aminopropyl)-3-(3-chloro-4-cyanophenyl)-1H-pyrazole-4-carbonitrile (100 mg, 0.350 mmol). The product was purified by recrystallization from diethyl ether and diethyl ether/ethanol, respectively. Finally the product was also run through flash chromatography. Yield 34.1%. 1H-NMR (400 MHz; DMSO-d6): δ 1.15 (d, 3H), 3.67 (s, 3H), 4.36-4.51 (m, 3H), 7.56 (d, 1H), 7.69 (d, 1H), 7.98 (dd, 1H), 8.04-8.10 (m, 2H), 8.15 (dd, 1H), 8.69 (s, 1H).
