A Facile Synthesis of Bromo-Substituted Benzofuran Containing Thiazolidinone Nucleus Bridged with Quinoline Derivatives: Potent Analgesic and Antimicrobial Agents

Abstract

Treatment of 5-bromo-2-acetyl benzofuran with hydrazine followed by condensation of the resulting hydrazone with different quinoline derivatives gave the corresponding Schiff bases. Reaction of these Schiff bases with thioacetic acid furnished the target thiazolidinone molecule. Some of the newly synthesized compounds show promising analgesic and antimicrobial activity.
