実験手順

A solution of [1-(3-bromopropyl)-7-(diethylamino)-1H-benzimidazol-2-yl](2,4-dichlorophenyl)methanone (Reference example 211, 360 mg, 0.745 mmol) and triphenylphosphine (586 mg, 2.23 mmol) in acetonitrile (5 mL) was stirred for 60 h at 80° C. The reaction mixture was concentrated in vacuo. Toluene (5 mL), tetrahydrofuran (1 mL), and potassium tert-butoxide (85%, 83.6 mg, 0.745 mmol) was added at room temperature. After 1 h, the reaction mixture was diluted with ethyl acetate, washed with brine, dried over sodium sulfate, filtrated, and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with a 5-25% ethyl acetate/n-hexane gradient mixture to afford the desired product as pale yellow solid (65.5 mg, 0.170 mmol, 23%).
