실험 절차

To a stirred suspension of 10-chloro-1-(2-chloro-4-methoxyphenyl)-2,3,4,5-tetrahydro-1H-[1,3]diazepino[1,2-a]benzimidazole-7-carbaldehyde (267 mg, 0.684 mmol) in tetrahydrofuran (7 mL) and a solution of ethyl magnesium bromide in diethyl ether (3.0 M, 274 μL, 0.821 mmol) was added at 0° C. After 15 min, the reaction mixture was quenched with aqueous ammonium chloride, diluted with ethyl acetate, washed with water and brine, dried over sodium sulfate, filtrated, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel eluting with a 10-40% ethyl acetate/n-hexane gradient mixture to give the title compound as a colorless solid (137 mg, 0.325 mmol, 48%).
