4-(4-Ethoxyphenyl)-5-(4-methoxyphenyl)-2,4-dihydro-3<em>H</em>-1,2,4-triazol-3-one

Abstract

A new triazol-3-one resulted unexpectedly from the reduction reaction of a heterocyclic thioketone using sodium borohydride in pyridine containing a small amount of water. The structure of the new compound was characterised using FT-IR, 1D and 2D NMR, and HRMS spectroscopic methods.
