実験手順

2-Bromopropionitrile (10 uL, 0.120 mmol) was added to a mixture of [4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazol-1-yl]-[piperazin-1-yl]-methanone hydrochloride and diisopropylethylamine (42 uL, 0.240 mmol) in dimethylformamide (1.0 mL). The reaction was stirred at room temperature overnight. Evaporation of the solvent and purification of the crude residue by flash chromatography over silica gel using 1-2% methanol in methylene chloride gave 3-{4-[4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazole-1-carbonyl]-piperazin-1-yl}-propionitrile, which was dissolved in dilute hydrochloric acid (0.5 N, 1 mL) and lyophilized to give 3-{4-[4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-4-trifluoromethyl-phenyl)-4,5-dihydro-imidazole-1-carbonyl]-piperazin-1-yl}-propionitrile hydrochloride as an off-white powder (20 mg, 39% yield). LR-MS (APCI): 644.4 [(M+H)+].
