실험 절차

To a stirred suspension of (2,4-dichlorophenyl)[7-(diethylamino)-1-(3-hydroxypropyl)-1H-benzimidazol-2-yl]methanone (404 mg, 0.961 mmol) and tetrabromomethane (637 mg, 1.92 mmol) in acetonitrile was added triphenylphosphine (504 mg, 1.92 mmol). After 15 min, the reaction mixture was diluted with ethyl acetate, washed with aqueous sodium hydrogen carbonate and brine, dried over sodium sulfate, filtrated, and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with a 0-30% ethyl acetate/n-hexane gradient mixture to afford the desired product as yellow solid (407 mg, 0.842 mmol), 88%).
