Procedure

Under nitrogen, to a solution of N-allyl-N-phenyl-benzyloxycarbonylamine (5.5 g) in dichloromethane (50 ml) was added m-chloroperbenzoic acid (3.9 g) at 5° C., and the mixture was stirred at room temperature for 3 days. The resulting mixture was poured into aqueous sodium hydrogensulfite and extracted with ethyl acetate. The organic layer was successively washed with saturated aqueous sodium hydrogencarbonate and brine, dried over anhydrous magnesium sulfate and evaporated in vacuo. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=10:1 to 5:1) to give 1-(N-benzyloxycarbonyl-N-phenylamino)-2,3-epoxypropane (2.2 g).
