실험 절차

369 mg of (2S, 4S)-4-(4-methoxybenzylthio)-2-(1-methyl-2-pyrrolidinylethylcarbamoyl)-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (prepared as described in Preparation 2) were suspended in 720 μl of anisole, and the suspension was placed on an ice bath. Maintaining the suspension on the ice bath, 3.6 ml of trifluoroacetic acid and 128 μl of trifluoromethanesulfonic acid were added to it, and it was then stirred for 1 hour at room temperature. At the end of this time, the solvent was removed by distillation under reduced pressure. The residue was washed with diethyl ether by repeated decantation and dried under reduced pressure, to give 440 mg of the title compound.
