Hydrogen Peroxide → HCID 66975222, compound

Participants

Reaction Steps

To a solution of tert-butyl (6RS,7RS)-6-(cyanomethyl)-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (900 mg) in methanol (7 mL)-water (2 mL) were added saturated aqueous sodium hydrogen carbonate (1 mL) and 35% aqueous hydrogen peroxide (3 mL), and the mixture was stirred for 3 days. To the reaction mixture was added saturated aqueous sodium thiosulfate solution, and the mixture was extracted twice with ethyl acetate. The combined organic layers were washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (492 mg).
