실험 절차

3-Bromo-5-nitroaniline (6.45 g, 29.7 mmol) was dissolved in dichloromethane (149 mL) and pyridine (2.88 mL, 35.7 mmol). The solution was cooled to 0° C. and then, acetyl chloride (2.325 mL, 32.7 mmol) was added dropwise. The reaction mixture was stirred at 0° C. for 1 hour. The reaction was diluted with water and dichloromethane and the organic phase was dried over sodium sulfate and was concentrated to dryness. N-(3-bromo-5-nitrophenyl)acetamide was isolated as a beige powder (7.86 g, 30 mmol, 100%) and was of sufficient purity to carry forward without further purification.
