Reaction Steps

(S)-N-[[3-[4-[4-[(2-cyanophenyl)sulfonyl]-1-piperazinyl]-3-fluorophenyl]-2-oxo-5-oxazolidinyl]methyl]acetamide (VIII-G, R1═COCH3, R9=2-cyanophenyl, X1═F, X2═H) (0.5 g) is suspended in 10 niL of methanol. Monoperoxyphthalic acid, magnesium salt hexahydrate (80% pure, 0.616 g) is added and the reaction mixture is stirred at room temperature for 2 hours. The reaction is concentrated and the resulting oil is chromatographed on silica gel using 7% methanol (saturated with ammonia) in chloroform as eluent to afford 0.33 g of the N-oxide.
