Syntheses of diheterocyclic compounds based on 2-thioacetohydrazide-5,7- dimethyl-1,2,4-triazolo[1,5-a]-pyrimidine

Abstract

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. © 2008 by the authors; licensee Molecular Diversity Preservation International.
