To a solution of methyl N-[(6-chloro-2-naphthyl)sulfonyl]-N-{(3S)-1-[(1S)-1-methyl-2-morpholin-4-yl-2-oxoethyl]-2-oxopyrrolidin-3-yl}glycinate [Example 55] (0.010 g) in THF (2 ml) was added lithium hydroxide (0.003 g) in water (2 ml), and the resultant solution stirred for 16 h. The mixture was acidified to pH5 using hydrochloric acid (2N), and then concentrated under reduced pressure. The residue was purified using mass directed preparative h.p.l.c. to give the title compound (0.006 g) as a white solid.
