Procedure
The title compound is prepared from 3-(3-(S)-amino-2-oxopyrrolidin-1-ylmethyl)benzonitrile hydrochloride as in EXAMPLE 24, Part B using 2-chloroethanesulfonyl chloride in place of 6-methoxynaphthalene-2-sulfonyl chloride. The crude product is purified by column chromatography in a gradient of 10% EtOAc/CH2Cl2 to 40% EtOAc/CH2Cl2 to afford the title compound as a solid.
