Studies on Condensed Heterocyclic Compounds. XIII. 6-(4-Methylphenyl)-3-(1-naphthylmethylene)-s-triazolo[3,4-b][1,3,4]thiadiazole

6-(4-Methylphenyl)-3-(1-naphthylmethylene)-s-triazolo[3,4-b][1,3,4]thiadiazole, C₂₁H₁₆N₄S, was prepared by cyclization of 3-(1-naphthylmethylene)-4-amino-5-mercapto-1,2,4-triazole with p-methyl benzoic acid in the presence of phosphorus oxychloride. The structure of the compound was determined by elemental analysis, IR and ¹H NMR spectroscopy, and X-ray diffraction. The phenyl group and the heteronucleus are almost coplanar. The dihedral angle between the naphthyl group and the heteronucleus is 83.54 ± 0.06°.
