실험 절차

To a solution of 4-bromo-2-ethylaniline (50 g, 0.25 mol) in dichloromethane (250 ml) is added triethylamine (63.24 g, 0.62 mol) and the mixture is stirred at room temperature for 30 minutes. The reaction mixture is cooled to 0° C. and acetyl chloride (39.25 g, 0.5 mol) is added dropwise. The reaction mixture is stirred at 25-30° C. for 60 minutes, then poured into water, and the two phases separated. The organic phase is washed with water, dried over anhydrous sodium sulfate, filtered and the filtrate is evaporated under reduced pressure to yield N-(4-bromo-2-ethylphenyl)acetamide (40 g).
