실험 절차

0.108 ml of methyl fluorosulfonate was added dropwise at room temperature to a solution of 0.38 of (2S, 4S)-2-carbamoyl-1-(2-hydroxyethyl)-4-(4-methoxybenzylthio)pyrrolidine dissolved in 7.5 ml of dry methylene chloride, and the mixture was stirred at the same temperature for 2 hours. At the end of this time, the solvent was removed by distillation under reduced pressure, and the residue was washed by decantation with diethyl ether and dried under reduced pressure, to afford 0.396 g of the title compound as an oil.
