Procedure

(S)-N-[[3-[3,5-Difluoro-4-[4-(hydroxyacetyl)- 1-piperazinyl]-phenyl]-2-oxo-5-oxazolidinyl]methyl]- acetamide (VIII-A, R1═COCH3, R2═H, X1═X2═F) (0.13 g) is dissolved in 5 mL of methanol. Monoperoxyphthalic acid, magnesium salt hexahydrate (80% pure, 0.2 g) is added and the resulting suspension is stirred at 25° C. for 72 hours. An additional 0.2 g of monoperoxyphthalic acid is added and the reaction is stirred an additional 48 hours. The reaction mixture is filtered and the filtrate is concentrated to afford a light-yellow oil. This material is chromatographed on silica gel using 20% methanol (saturated with ammonia) in chloroform as eluent to afford 55 mg of the N-oxide.
