실험 절차

A solution of 1-benzyl-3-t-butyldimethylsilyloxymethylpyrrolidine (60.10 g) and allyl chloroformate (25.27 ml) in toluene (600 ml) was heated at 60° C. for one hour. The mixture was concentrated under reduced pressure to give a syrup. The syrup was subjected to a column chromatography on silica gel (500 g), and eluted with a mixture of ethyl acetate and hexane (1:9-3:7, V/V) to give 1-allyloxycarbonyl-3-t-butyldimethylsilyloxymethylpyrrolidine (30.00 g).
