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]benzimidazol-7-yl]methanol (313 mg, 0.798 mmol) in acetonitrile (8 mL) was added Dess-Martin reagent (406 mg, 0.958 mmol) at room temperature. After 15 min, the reaction mixture was diluted with ethyl acetate, washed with aqueous sodium hydrogen carbonate and brine, dried over sodium sulfate, filtered, and concentrated in vacuo to give the title compound as a pale brown solid (267 mg, 0.684 mmol, 85%).
