To a stirred solution of 10-chloro-1-(2,4-dichlorophenyl)-4,5-dihydro-1H,3H-[1,4]oxazepino[4,3-a]benzimidazole-7-carbaldehyde (88.1 mg, 0.223 mmol) in tetrahydrofuran (2 mL) was added a solution of cyclopropyl magnesium bromide in tetrahydrofuran (1.0 M, 357 μL, 0.357 mmol) at 0° C. After 0.5 h, 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 10-50% ethyl acetate/n-hexane gradient mixture to give the title compound as a colorless solid (81.4 mg, 0.186 mmol, 83%).
