Procedure

20 ml of sulfuric acid are cooled to 0° C. and then 5 g (13.8 mmol) of 7-bromo-5-bromomethyl-2,3-dimethoxy-quinoxaline are added. After a further 15 minutes, 1.46 g (1.05 equiv.) of potassium nitrate are added and the mixture is stirred for 15 hours at 20° C. The mixture is poured onto ice, and the solid is filtered off and washed with water. The title compound is obtained in the form of a beige solid.
