2-Formylquinoxaline-1,4-dioxide hydrate, 2 g (0.01 mole) was dissolved in 100 ml of warm methanol. Ten drops of triethylamine were added with stirring and 1 g (0.016 mole) of nitromethane was added. The heat source was removed and the reaction mixture was allowed to cool to room temperature. The methanol was removed by evaporation and the residue was recrystallized from water. There was obtained 2-(2-nitro-1-hydroxyethyl)quinoxaline-1,4-dioxide. It was designated P-2231 for convenience.
