Procedure
A solution of benzyloxycarbonyl chloride (4.28 ml, 30.0 mmol) in dichloromethane (15 ml) was added dropwise to a solution of (1R,5S)-7-benzyl-2-oxo-7-azabicyclo[3.3.0]octane (1.31 g, 6.10 mmol) in dichloromethane (20 ml) while cooling with ice, and the mixture was stirred at room temperature for 16 hours. The solvent was removed by evaporation, and the residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=1:1) to give 1.36 g (5.24 mmol, 86%) of the title compound as a colorless oily substance.
