Reaction Steps

To a solution of (4R)-4-methyl-4-{2-[5-(5-phenylpentanoyl)pyrrol-2-yl]ethyl}-1,3-oxazolidin-2-one (41.0 mg, 0.12 mmol) obtained in Example (42a) in a mixed solvent of methanol (2 ml), tetrahydrofuran (2 ml) and water (2 ml) was added 10N aqueous sodium hydroxide solution (0.12 ml, 1.17 mmol), and the resulting mixture was refluxed for 4 days. After cooling to room temperature, water was added to the reaction mixture, and the resulting mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. After filtration, the solvent was removed in vacuo, and the residue was purified by chromatography on a basic silica gel column (NH type) using a mixed solvent of dichloromethane and methanol (20:1) as the eluent to afford the title compound (30.0 mg, yield: 79%).
