Mode opératoire

A solution of 6-chloro-N-{(3S)-1-[(1S)-1-methyl-2-morpholin-4-yl-2-oxoethyl]-2-oxopyrrolidin-3-yl}naphthalene-2-sulfonamide (0.01 g) in THF (2 ml) was cooled to −78° C. under nitrogen, and treated with lithium bis(trimethylsilyl) amide (1.0M solution in THF; 0.026 ml), followed by bromoacetonitrile (0.013 g). The resultant solution was allowed to reach room temperature and stirred for a further 16 h. The mixture was then cooled to −78° C. and further lithium bis(trimethylsilyl) amide (0.026 ml) added. After reaching room temperature, the reaction mixture was stirred for a further 18 h and then quenched by the addition of methanol (1 ml). The resultant solution was concentrated under reduced pressure and the residue purified by mass directed preparative h.p.l.c. to give the title compound (0.003 g) as a white solid.
