実験手順
To a solution of N-(5-methoxy-2-methylphenyl)acetamide in acetic acid (40 mL) was added Br2 (3 g, 19 mmol) slowly. The mixture was capped and stirred at 50° C. for 5 hours. The reaction was cooled to room temperature, then quenched with sodium sulfite aqueous solution, and extracted with ethyl acetate (3×50 mL). The combined organic layer was dried over Na2SO4 and concentrated to give crude N-(4-bromo-5-methoxy-2-methylphenyl)acetamide as a brown oil, which was used in the next step without further purification.
