Reaktionsschritte
A solution of 1-allyloxycarbonyl-3-t-butyldimethylsilyloxymethylpyrrolidine (29.95 g) in a mixture of concentrated hydrochloric acid (15 ml) and methanol (150 ml) was stirred at ambient temperature for one hour. A 28% solution of sodium methoxide in methanol (35 ml) was added to the mixture. Insoluble material was filtered off and the filtrate was concentrated under reduced pressure to give a syrup. The syrup was subjected to a column chromatography on silica gel (400 g) and eluted with ethyl acetate to give 1-allyloxycarbonyl-3-hydroxymethylpyrrolidine (19.01 g).
