Abstract
The solid‐phase synthesis of 2‐(N‐arylamino)benzothiazoles is achieved by reacting substituted thioureas with polymer‐supported tribromide. A series of 2‐(N‐aryl)aminobenzothiazoles is prepared in high yields under microwave irradiation. The method has several advantages such as short reaction time, good yields, and environmentally benign procedure. Moreover, the catalyst could be recovered conventionally and reused at least four times without loss of activity. Therefore, it would be of great interest to synthesize some of the 2‐(N‐arylamino)benzothizoles under green chemistry conventions.
