실험 절차

To a solution of methyl 3-hydroxyisothiazole-5-carboxylate (300 mg, 1.73 mmol) in MeOH (2 mL) is added 1N NaOH (6 mL, 6 mmol). After stirring at room temperature for 2 hours, the crude is concentrated under reduced pressure to remove MeOH and is diluted with EtOAc. The organic layer is washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure to give 3-hydroxyisothiazole-5-carboxylic acid (250 mg).
