Good approach - less yields. Better methods reported already


This paper reports the synthesis of 2-arylbenzothiazoles via cyclocondensation of 2-aminothiophenol with various aldehydes. Polyethylene glycol-400 (PEG-400) has been used as both solvent and catalyst for the process. The procedure applied, is easy to reproduce and...
