The work presents 2-amino-5-methyl-1,3,4-thiadiazole formation simulation by DFT/B3LYP/6-31G(d,p), DFT/B3LYP/6-311+G(2d2p), MP2/6-311+G(2d2p) methods. It was established that the 2-amino-5-methyl-1,3,4-thiadiazole formation is a complicate multi-stage process that occurs through a number of elementary chemical transformations, the activation barriers of which were estimated.
