Procedure
30 g (0.106 mol) of 6-chloro-1-(2-ethylbutyl)-2,3(1H,4H)-quinoxalinedione were dissolved in 350 ml of concentrated sulfuric acid and cooled to 0°C. Then, at 0° C., 10.8 g of potassium nitrate were added a little at a time, and the solution was stirred for 1.5 h. The mixture was then poured into ice-water, and the precipitate was filtered off with suction, washed with water and dried to yield 31 g (91%) of the product. Melting point 232°-233° C.
