Reaction Steps

4-Ethylacetophenone (26.72 mmol, 4 mL) was dissolved in dimethyl sulfoxide (27 mL), and 48% hydrobromic acid (11 mL) was gradually added at room temperature. After overnight stirring at 70° C., the reactor was cooled to room temperature. The reaction solution was poured into water (50 mL) and stirred for about 1 hour. 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 (2.44 g, yield 56%).
