실험 절차

To methyl (2-(5-fluoro-1-methyl-3-indolyl)-7-fluoro-6-benzoxazolyl)acetate (279 mg, 0.78 mmol) were added THF/methanol (1/1, 20 ml) and 0.25N NaOH (9.4 ml, 2.35 mmol). The resulting mixture was stirred at room temperature for 18 hours. The reaction mixture was poured in 1N HCl to acidify the mixture therewith, followed by extraction with chloroform/methanol (10/1). The extract was dried over anhydrous sodium sulfate, and distilled under reduced pressure to remove the solvent. The crystals thus obtained were collected by filtration under reduced pressure, washed with hexane, and dried under reduced pressure to give (2-(5-fluoro-1-methyl-3-indolyl)-7-fluoro-6-benzoxazolyl)acetic acid (208 mg, 78%) as a brown crystalline powder.
