Participants

Reaction Steps

To a solution of tert-butyl (6R,7R)-6-[(acetylamino)methyl]-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (180 mg) in THF (4 mL) was added sodium hydride (32 mg, 60%) under ice-cooling, and the mixture was stirred under ice-cooling for 30 min. To the reaction mixture was added methyl iodide (0.107 mL) under ice-cooling, and the mixture was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate. The diluted solution was washed with distilled water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (100 mg).
