Procedure

To a solution of (3S)-3-amino-1-[(1S)-1-methyl-2-morpholin-4-yl-2-oxoethyl]pyrrolidin-2-one (0.077 g) in anhydrous acetonitrile (2 ml) were added 5-chloro-1-benzofuran-2-sulfonyl chloride (0.043 g) in acetonitrile (2 ml) and pyridine (0.057 ml), and the mixture was stirred at room temperature for 72 h. Saturated ammonium chloride solution (2 ml) was added and the resultant mixture stirred at room temperature for 20 min. The mixture was concentrated under reduced pressure and the residue partitioned between chloroform and hydrochloric acid (2M). The organic layer was washed with saturated sodium bicarbonate and brine. The organic layer was isolated, dried (over magnesium sulphate) and concentrated under reduced pressure to give the title compound (0.043 g) as a white solid.
