실험 절차
To a slurry of 5-fluoro-7-nitro-1H-indole-2,3-dione (3 g, 14.2 mmol) in aqueous 5N NaOH solution (30 mL) was added slowly an aq. solution of 33% hydrogen peroxide (3 mL) at 0° C. After completion of the addition, the reaction mixture was stirred at room temperature for 4 h. After completion of the reaction, the reaction mixture was acidified with 2N HCl and the resulting precipitate was filtered, washed with water (2-3 times) and dried under vacuum to obtain the title compound as yellow solid (2 g, 70.17%).
