3‐(4′‐Pyridyl)‐4‐amino‐5‐mercapto‐1,2,4‐triazole (1) reacted with aroyl isothiocyanates 2a‐1 to yield twelve novel 3‐(4′‐pyridyl)‐6‐aroylamino‐ S ‐triazolo [3,4‐ b ]‐1,3,4‐thiadiazoles, 4a‐1 . Triethylamine was necessary for the condensation of 1 with phenyl isothiocyanate ( 3 ) to give 3‐(4′‐ pyridyl)‐6‐phenylamino‐ S ‐triazolo [3,4‐ b ]‐1,3,4‐thiadiazole ( 6 ). The structures were confirmed by the elemental and spectral analyses. Their antibacterial activity against B . Subtilis, E. Coli, E. aerogenes and S. aureus was observed preliminary.
