Two regioselective synthetic approaches for the title compounds 7 via reaction of hydrazonoyl halides 1 with 3‐methylthio‐5‐phenyl‐1,2,4‐triazole 3 and base‐catalyzed cyclization of N‐phenyl‐N‐(5‐phenyl‐s‐triazol‐3‐yl)thiohydrazides 6 are described. The mechanisms of the reactions studied and the biological activity of the isolated products 6 and 7 are pointed out.
