Abstract

A simple and convenient approach to 2-(4-aminophenyl)benzothiazole derivatives by condensation of o-aminothiophenol with (un)substituted p-aminobenzoic acid under the action of melamine formaldehyde resin (MFR) supported sulfuric acid under microwave irradiation (MW) and solvent-free conditions has been developed. Structures of the corresponding products were elucidated by IR, 1H NMR spectra, and elemental analysis. The resin could be easily recovered and reused for subsequent reactions.
