NBS is an efficient, readily available and cheap catalyst for the synthesis of 2-substituted benzothiazole derivatives by condensation of 2-aminothiophenol and aldehydes under sonication conditions by application of green solvents. This protocol is very simple with easy workup and good to excellent yields of products. On completion of reaction the products were characterized by IR, NMR and Mass Spectra.
