4-Methoxy-3-nitro-1,2-benzenediamine (6) has been prepared through nitration of 5-methoxy-2,1,3-benzoselenadiazole, followed by reductive removal of the selenium.Cyclocondensation of 6 with α-dicarbonyl compounds afforded the title quinoxalines, some of them novel and not easily obtainable by direct nitration.Methyl- or phenylglyoxal gave mixtures of quinoxalines in proportions strongly influenced by the acidity of the reaction medium.
