Abstract A new in principle method for the synthesis of 6-aryl (hetaryl)-3, 5-diamino-1, 2, 4- triazines by decomposition of pre-synthesized tetrazolo [1, 5-b][1, 2, 4] triazines was developed. The advantages of this method over traditional methods were demonstrated using the synthesis of a modern antiepileptic preparation lamotrigine, as an example.
