12-Imino-12H-[1]benzo-v-triazino[3,4-a]quinazoline has been prepared by alumina-catalysed cyclisation of 1,3-di-o-cyanophenyltriazene and its properties compared with those of the isomeric 7-imino-7H-[1]benzo-v-triazino[4,3-b] quinazoline. The triazino[3,4-a]quinazoline is involved as an intermediate in certain reactions of 1,3-di-o-cyanophenyltriazene; thus, the triazene affords, on reduction with stannous chloride in ethanol, 11-aminoindazolo[3,2-b] quinazoline.
