Hydrazidine; VI: Synthesis of N1,N2-dimethylhydrazidines and 1,2-dihydro-1,2-dimethyl-1,2,4,5-tetrazines

Starting with (thiobenzoylthio)acetic acids 1 N1,N2-dimethylbenzohydrazide hydrazones 5 were prepared. Cyclization of 5 with trimethyl orthobenzoate affords 1,2-dihydro-1,2-dimethyl-1,2,4,5-tetrazines 6.
