Potassium Nitrate → HCID 10538061, compound

Participants

Reaction Steps

In 20 ml of sulfuric acid was dissolved 1.34 g of 7-fluoro-1-hydroxyquinoxaline-2,3-(1H,4H)-dione followed by addition of 0.76 g of potassium nitrate under ice-cooling. The mixture was cooled to at room temperature, and after 1 hour, the reaction mixture was poured in ice-water. The resulting crystals were recovered by filtration, rinsed with water and recrystallized from ethanol-water to provide 0.82 g (50%) of 7-fluoro-1-hydroxy-6-nitroquinoxaline-2,3-(1H,4H)-dione.
