The action of a nitrating mixture on benzo-1,5-diazepine

It has been shown that the action of a mixture of nitric and sulfuric acids on 2,4-dimethylbenzo-1, 5-diazepine leads to processes of nitration, hydrolytic cleavage, and oxidation with simultaneous isomerization, with the formation of N,N-diacetyl-4-nitro-1,2-phenylenediamines, benzotriazole, and 2-acetyl-3-methylquinoxaline.Translated from Khimiya Geterotsiklicheskikh Soedinenii, Vol. 6, No. 8, pp. 1133–1134, August, 1970.
