A mixture of 4-dimethylaminobenzonitrile (2.92 g, 20 mmol) and N-bromosuccinimide (3.56 g, 20 mmol) in dichloromethane (50 mL) was stirred at room temperature overnight. The solution was washed with water (20 mL), dried over magnesium sulfate and concentrated to afford 3-bromo-4-dimethylaminobenzonitrile as a white solid (4.27 g).
