Syntheses of Diheterocyclic Compounds Based on 2-Thioacetohydrazide-57-dimethyl-124-triazolo15-a-pyrimidine

摘要

The syntheses of some diheterocyclic compounds from 2-thioacetohydrazide-5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (>1) are described. Compound >1 can be converted into triazoles, 1,3,4-oxadiazoles, and 1,3,4-thiadiazoles. The structures of the intermediates and the target compounds were confirmed by ¹H-NMR, MS and elemental analyses.
