Procedure

To a solution of 4,5-di-(4-chlorophenyl)imidazole (300 mg, 1.0 mmol) from Step A and methyl iodide (0.10 mL, 2.0 mmol) in DMF (5 mL) was added sodium hydride (80 mg 60% in mineral oil, 1.5 mmol) all at once at rt. After stirring for 1 hr, the reaction was quenched into water and extracted twice with ethyl acetate. The organic layers were washed with brine, dried over sodium sulfate, and evaporated. The residue was purified by flash chromatography (10% methylene chloride, 30% ethyl acetate in hexanes) to provide the title compound as a white solid.
