Reaction Steps

A solution of 1-[4-(dimethylamino)phenyl]ethanone (500 mg, 3.1 mmol) in DMF-DMA (10 mL), toluene (10 mL), and AcOH (2 drops), was heated under reflux conditions for 48 h. The solution was concentrated and purified by flash column chromatography (hexanes:EtOAc=8:2˜1:1) to give the title compound (121 mg, 18%) as a yellow solid.
