Trimethylsilyl isocyanate → HCID 66975736, compound

Participants

Reaction Steps

To a solution of tert-butyl (6RS,7SR)-6-(aminomethyl)-7-(3,4-dichlorophenyl)-1,4-oxazepane-4-carboxylate (125 mg) in THF (1.5 mL) was added trimethylsilyl isocyanate (57.7 mg), and the mixture was stirred at room temperature for 1.5 hr. The reaction mixture was concentrated under reduced pressure, and the residue 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. The residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (160 mg).
