Reaction Steps
3,4-dimethylacetophenone (13.52 mmol, 2.0 g) was dissolved in dimethyl sulfoxide (13 mL), and 48% hydrobromic acid (5.4 mL) was gradually added at room temperature. After 16 hours of stirring at 70° C., the reactor was cooled to room temperature. The reaction solution was poured into water and stirred for about 16 hours. The precipitated solid was recovered by filtration, washed with water and dried by means of a vacuum pump to give the desired product as a white solid (1.234 g, yield 57%).
