실험 절차

To a stirred solution of [10-chloro-1-(2,4-dichlorophenyl)-4,5-dihydro-1H,3H-[1,4]oxazepino[4,3-a]benzimidazol-7-yl](cyclopropyl)methanol (81.4 mg, 0.186 mmol) in acetonitrile (2.5 mL) was added Dess-Martin reagent (94.7 mg, 0.223 mmol) at room temperature. After 5 h, the reaction mixture was diluted with ethyl acetate, quenched with aqueous sodium hydrogen carbonate, washed with water and brine, dried over sodium sulfate, filtered, 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 (67.1 mg, 0.154 mmol, 83%).
