Reaction Steps

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 pH 5 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.
