To a solution of (2S,4R)-1-benzyloxycarbonyl-2-hydroxymethyl-4-methanesulfonyloxypyrrolidine (48.0 g) in dichloromethane (250 ml) was added triethylamine (26.4 ml) and methanesulfonyl chloride (14.3 ml) under ice-cooling and the mixture was stirred at the same temperature for 30 minutes. The reaction mixture was washed in turn with water (100 ml) and saturated aqueous sodium chloride (100 ml), dried over anhydrous magnesium sulfate and evaporated in vacuo to give (2S,4R)-1-benzyloxycarbonyl-4-methanesulfonyloxy-2-methanesulfonyloxymethylpyrrolidine (48.1 g).
