Procedure
To a solution of 4-(3-Amino-2-oxopyrrolidine-1-ylmethyl)thiophene-2-carbonitrile hydrochloride (0.43 g, 1.8 mmol), prepared as in EXAMPLE 122, in 10 mL of CH2Cl2 is added 7-methoxynaphthalene-2-sulfonyl chloride (0.51 g, 2 mmol) and triethyl amine (0.55 g, 5.4 mmol). After 16 hours, the solution is diluted with EtOAc and H2O. The layers are separated. The organic layer is washed with 1 N HCl, sat. NaHCO3 and sat. NaCl. The organic layer is dried over MgSO4, filtered and concentrated. The crude product is purified by column chromatography eluting with gradient of 10% EtOAc/CH2Cl2 to 20% EtOAc/CH2Cl2 to afford the title compound (0.50 g, 1.22 mmol) as a white solid.
