Methyl iodide → tert-butyl (6R,7S)-7-(3,4-dichlorophenyl)-6-(methylamino)-1,4-oxazepane-4-carboxylate

Participants

Reaction Steps

To a solution of tert-butyl (6R,7S)-6-amino-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (150 mg) in THF (4 mL) was added methyl iodide (0.026 ml) at room temperature, 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 (30 mg).
