To 3-{3-(3-acetyl-2-oxoimidazolidin-1-yl)-4-[4-(3,5-dimethylpyridin-2-yl)piperazine-1-carbonyl]phenyl}oxazolidin-2-one (156 mg) described in Example 209 were added methanol (2 mL) and 1N aqueous sodium hydroxide solution (0.31 mL), and the mixture was stirred at 50° C. 1N hydrochloric acid (0.31 mL) and water were added, and the mixture was extracted with ethyl acetate. The solvent was evaporated, and the residue was purified by column chromatography (ethyl acetate:methanol) to give the title compound (13 mg).
