実験手順

(R)-3-[2-fluoro-4-(piperazine-1-carbonyl)phenyl]-4-methoxymethyloxazolidin-2-one (343 mg) described in Preparation Example 94 was dissolve in N,N-dimethylformamide (2 mL), 2,3,5-trichloropyridine (275 mg) and potassium carbonate (562 mg) were added and the mixture was stirred at 100° C. To the reaction mixture was added ethyl acetate under ice-cooling and insoluble materials were filtered off. Water was added to the filtrate and the mixture was extracted with ethyl acetate. The organic layer was washed twice with saturated brine, and dried over sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by column chromatography (chloroform:methanol) to give the title compound (240 mg).
