Procedure:
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.

After stirring at 60° C. for 4 h, 6 M aqueous HCl (0.3 mL) was added to the mixture to adjust the pH to 10. After removal of the solvent at reduced pressure, the residue was diluted with DMF (5 mL). Then, triethylamine (2.6 mL, 19 mmol) and ammonium chloride (1.02 g, 19 mmol) were added. After stirring at room temperature for 5 min, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.09 g, 5.70 mmol) and 1-hydroxybenzotriazole (0.77 g, 5.70 mmol) were added to the mixture and the stirring was continued for 17 h. Then, water and EtOAc were added to quench the reaction. The organic materials were extracted with EtOAc. The combined extracts were washed with water and brine, dried over Na2SO4 and filtered. After removal of the solvent at reduced pressure, the residue was purified by column chromatography (Purif, silica gel, hexane to 70:30 hexane/EtOAc) to give the title compound (130 mg, 48%) as a yellow solid:
