Participants

Reaction Steps

To a solution of (2S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-2-methoxymethylpyrrolidine (2.8 g) and methanesulfonyl chloride (1.12 ml) in dichloromethane (30 ml) was added dropwise triethylamine (2.38 ml) at 0° C. After 30 minutes, the reaction mixture was washed in turn with 1N-hydrochloric acid, water and brine. The organic layer was dried over magnesium sulfate and evaporated to give an oil, which was chromatographed on silica gel (300 ml) eluting with a mixture of hexane and ethyl acetate (1:1, V/V) to give (2S,4R)-1-(tert-butoxycarbonyl)-4-methanesulfonyloxy-2-methoxymethylpyrrolidine (3.61 g).
