چکیده مقاله

A highly efficient and simple protocol for the preparation of 2-aminobenzothiazoles through the reaction of potassium thiocyanate and substituted anilines in the presence of nano-BF3/SiO2 as a reusable heterogeneous catalyst is described. In this method, all of the 2-amino-substituted benzothiazoles were obtained in high to excellent yields and short reaction times under mild conditions. The structures of the resulting products were characterized and confirmed by melting point, FT-IR, 1H NMR and 13C NMR techniques.
