Procedure

To a solution of (2S,4R)-1-benzyloxycarbonyl-2-hydroxymethyl-4-t-butyldimethylsilyloxypyrrolidine (39.96 in dry pyridine (40 ml), acetic anhydride (40 ml) was added, and the resultant mixture was allowed to stand overnight. The reaction mixture was diluted with ethyl acetate, washed with aqueous sodium chloride solution, dilute hydrochloric acid, aqueous sodium chloride solution, aqueous sodium bicarbonate solution and aqueous sodium chloride solution in order and dried over magnesium sulfate. Removal of the solvent gave (2S,4R)-1-benzyloxycarbonyl-2-acetoxymethyl-4-t-butyldimethylsilyloxypyrrolidine.
