Procedure

In 22 ml of sulfuric acid was dissolved 1.6 g of 6-fluoro-1-hydroxyquinoxaline-2,3-(1H,4H)-dione followed by addition of 0.9 g of KNO3. The mixture was reacted at room temperature for 3 hours, after which it was poured in ice-water. The resulting crystals were recovered by filtration to provide 310 mg of 6-fluoro-1-hydroxy-7-nitroquinoxaline-2,3-(1H,4H)-dione.
