A convenient and efficient synthesis of previously unreported N-triazolide imidates and their reaction with 1,2,4-triazole-3,5-diamine to give regioselectively 5-substituted 2-amino[1,2,4]triazolo[1,5-a][1,3,5]triazin-7(6H)-ones is described. The structure of the reported bicyclic compounds has been unambiguously proven by X-ray crystallography.
