Reaction of 2-hydrazinocarbonylmethenethio-5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine with carbon disulfide in refluxing ethanol afforded 2-(5-mercapto-1,3,4-oxadiazol-2-ylmethylthio)-5,7-di-methyl-1,2,4-triazolo[1,5-a]pyrimidine, which was then treated with various benzyl halide in basic condition to yield 17 novel biheterocyclic derivatives. The structures of all compounds obtained were con-firmed by elemental analyses, 1H NMR and MS. Preliminary bioassay indicates that some compounds display antibacterial activity to certain extent.

Key words: 1,3,4-oxadiazole, bioactivity, 1,2,4-triazolo[1,5-a]pyrimidine
