Abstract
An environmentally benign and efficient process for the preparation of 3‐(substituted methylthio)‐4‐phenyl‐5‐ (3,4,5‐trimethoxyphenyl)‐4__H__‐1,2,4‐triazole was achieved by the reaction of 4‐phenyl‐5‐(3,4,5‐trimethoxyphenyl)‐ 4__H__‐1,2,4‐triazole‐3‐thiol with different halides in aqueous media mediated by indium trichloride in high yields.
