Reaction Steps
A 0.84 ml portion of methanesulfonyl chloride was added dropwise to a 30 ml dichloromethane solution of 3.5 g of 4-(methoxycarbonyl)phenyl (3R,4S)-3-(hydroxymethyl)-4-phenylpyrrolidine-1-carboxylate and 2.75 ml of triethylamine, and stirred at room temperature for 2Hours. Thereafter, its work-up was carried out in the standard method to obtain 4.3 g of 4-(methoxycarbonyl)phenyl (3R,4S)-3-{[(methylsulfonyl)oxy]methyl}-4-phenylpyrrolidine-1-carboxylate as a colorless amorphous substance. EP: 434.
