実験手順
The title compound was prepared using the method of Example 247 starting from 1-methyl-1H-imidazole-4-carboxylic acid and (S)-4-[1-(2-aminopropyl)-1H-pyrazol-3-yl]-2-chloro-6-fluorobenzonitrile (which can be prepared according to Example 34(c)). The crude product was purified by flash chromatography on silica gel by using CH2Cl2-MeOH as a gradient eluent (100:0-99:1). The resulting product was triturated in diethyl ether at RT to afford the title product. 1H NMR (400 MHz, DMSO-d6): 1.21 (31-1, d), 3.74 (3H, s), 4.26 (1H, distorted dd), 4.42 (1H, distorted dd), 4.56 (1H, m), 6.60 (1H, d), 7.43 (1H, d), 7.49 (1H, d), 7.50 (1H, d), 7.75 (1H, dd), 7.87 (1H, m), 7.97 (1H, d).
