A solution of tert-butyl (2S)-2-((3S)-3-{[(6-chloro-2-naphthyl)sulfonyl]amino}-2-oxopyrrolidin-1-yl)propanoate (1.31 g) in DMF (22 ml) was treated with potassium carbonate (0.786 g) followed by 2-bromoacetamide (0.48 g) and the resultant mixture stirred at room temperature for 22 h. Additional 2-bromoacetamide (0.4 g) and potassium carbonate (0.4 g) were added and the mixture was stirred at room temperature for 24 h. The reaction mixture was evaporated under reduced pressure and the residue partitioned between ethyl acetate and water. The separated organic layer was washed with water, dried (over magnesium sulphate) and evaporated under reduced pressure to give the title compound (1.4 g) as a white foam.
