Abstract
The new v-triazolyl[4,5-d]pyrimidines of the formula <IMAGE> where Q and Q1 are independently of each other a secondary or tertiary amino radical and X to X2 are each hydrogen or the substituents specified in Claim 1, are prepared by coupling an amine of the formula <IMAGE> with a diazonium salt of the formula <IMAGE> where Z is an anion, and subjecting the resulting o-aminoazo compound of the formula <IMAGE> to an oxidative ring closure.
