A simple and fast synthesis of 6-aryl-3-substituted-5H-[1,2,4]-triazolo[4,3-b][1,2,4]triazoles 4 in high yields has been developed by microwave assisted heterocyclization of N-(3-methylthio-5-substituted-4H-1,2,4-triazol-4-yl)benzenecarboximidamides 3 . The effectiveness of the microwave irradiation and conventional heating for the formation of compounds 4 has been investigated.
