With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.131106-70-2,6-(Trifluoromethyl)benzo[d]thiazole,as a common compound, the synthetic route is as follows.

General procedure: In a two-necked flask equipped with a reflux condenser were placed RhH(PPh3)4 (4 mol%, 11.5 mg), 1,2-bis(diphenylphosphino)ethane (8 mol%, 8.0 mg), 1,3-benzothiazole 5 (0.25 mmol, 27.3 mL), and (alpha-phenylthio)isobutyrophenone 6 (0.25 mmol, 64.0 mg) in chlorobenzene (0.25 mL) under an argon atmosphere, and the solution was heated at reflux for 3 h. The mixture was purified by flash column chromatography on silica gel giving 7 (55.8 mg, 92%) and isobutyrophenone 8 (34.3 mg, 93%) with the recovery of 5 (3.5 mg, 10%) and 6 (0.8 mg, 1%).

131106-70-2, 131106-70-2 6-(Trifluoromethyl)benzo[d]thiazole 14810650, athiazole compound, is more and more widely used in various fields.
