To a solution of (E)-2-(3-{[tert-butyl(diphenyl)silyl]oxy}-4-chlorophenyl)-N-{(3S)-1-[(1S)-1-methyl-2-morpholin-4-yl-2-oxoethyl]-2-oxopyrrolidin-3-yl}ethenesulfonamide (0.0078 g) in THF (0.3 ml) at −78° C. under nitrogen, tetra n-butylammonium fluoride (1M in THF, 0.014 ml) was added. The mixture was allowed to warm to room tempertaure over 3 days and then concentrated under reduced pressure. The residue was purified using mass directed preparative h.p.l.c. to give the title compound (0.0043 g) as a clear film.
