実験手順

4-Chloromethylbenzoyl chloride (140 mg, 0.74 mmol) was added to a cooled solution of triethylamine (0.20 mL, 1.44 mmol) and 4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-5-trifluoromethyl-phenyl)-4,5-dihydro-1H-imidazole (300 mg, 0.61 mmol). The reaction mixture was stirred at room temperature for 2 h. The reaction was diluted with methylene chloride and washed with water and brine, and dried over anhydrous sodium sulfate. The solvents were removed under reduced pressure and flash chromatography of the residue over silica gel using 10-25% ethyl acetate in hexanes gave [4,5-bis-(4-chloro-phenyl)-2-(2-ethoxy-5-trifluoromethyl-phenyl)-4,5-dihydro-imidazol-1-yl]-(4-chloromethyl-phenyl)-methanone (330 mg, 84%).
