Synthesis and Antitumor Activity of 2-N-,3-S-Substituted 5-(4-Benzyloxyphenyl)-1,2,4-Triazoles

Cyclization of substituted thiosemicarbazides in alkaline medium was used to synthesize the corresponding 3-thio-4-benzyl(cyclohexyl, allyl)-5-(4-benzyloxyphenyl)-1,2,4-triazoles. These compounds were 3-S-alkylated with ethylene chlorohydrin, chloroacetamide, 3-bromo-4-methoxybenzyl chloride, and chloroacetic, 2-bromopropionic, and 2-bromocaproic acids. Aminomethylation and oxymethylation reactions were studied. 2-N-Aminomethylene and 2-N-oxymethylenetriazoline-3-thiones were prepared. The antitumor activity of the compounds synthesized here were studied.
