A series of 3-(3-pyridyl)-6-substituted-s-1,2,4-triazolo[3,4-b]thiadiazoles was synthesized in good yields via condensation of 3-(3-pyridyl)-4-amino-5-thio-1,2,4-thiazoles with carboxylic acids in the presence of POCl3 and phase transfer catalyst tetrabutylammonium iodide (TBAI). The structures of the target compounds were confirmed by IR, 1H NMR, MS and elemental analyses, and the in vitro activity was also evaluated.

Key words: phase transfer catalysis, pyridyl triazolothiadiazole, synthesis, bioactivity
