反应详情

A mixture of 2-bromo-1-(naphthalen-1-yl)ethanone (1 g, 4.02 mmol), benzotriazole (530 mg, 4.42 mmol) and K2CO3 (560 mg, 4.02 mmol) in toluene (100 mL) was heated at reflux for 16 hours. The reaction was cooled to room temperature, washed with water, dried over sodium sulfate and concentrated. Purification by preparative thin layer chromatography (100% DCM) afforded 2-(1H-benzo[d][1,2,3]triazol-1-yl)-1-(naphthalen-1-yl)ethanone as a tan solid.
