Synthesis and antidepressant activity of di substituted-5-aryl-1,2,4-triazoles

A series of 5-aryl-1H-1,2,4-triazole-3-thiol (3) were synthesized. Alkylation of thiol group with N,N-dimethyl/diethyl/dicyclo hexyl-(2-chloro ethyl) amine gave compounds N,N-disubstituted-2-(5-aryl-1H-1,2,4-triazol-3-ylthio)ethanamine (4). These compounds were characterized on the basis of IR, 1H NMR, Mass spectral data, and elemental analysis. The newly synthesized compounds were screened for their antidepressant activity by using tail suspension test in mice.
