A facile and effective method for the synthesis of some benzothiazolederivatives is described. The method involves the action of aryl aldehyde and o-aminothiophenol in acetic acid resulting into in situ formation of the thiol substituted Schiff's base and its cyclization to 2-aryl benzothiazole upon prolonged heating.
