Novel 6‐aryl‐3‐[5‐methyl‐1‐(4‐methylphenyl)‐1,2,3‐tri‐azol‐4‐yl]‐ s ‐triazolo[3,4‐b]‐1,3,4‐thiadiazoles were synthesized by the condensation of 3‐[5‐methyl‐1‐(4‐methylphenyl)‐1,2,3‐triazol‐4‐yl]‐4‐amino‐5‐mercapto‐ s ‐triazole with various aromatic carboxylic acids in the presence of phosphorus oxychloride. The compounds were characterized by MS, IR, 1 H and 13 C NMR spectroscopy. The measured and calculated 13 C chemical shifts of the aromatic carbons were compared.
