Reaction Steps

A mixture of 2-bromo-4-isopropylaniline (5.05 g, 23.6 mmol), acetic anhydride (2.4 mL, 25 mmol), and triethylamine (3.5 mL, 25 mmol) in dichloromethane (25 mL) was stirred at ambient temperature for 4 days. The mixture was diluted with dichloromethane, washed sequentially with saturated aqueous Na2CO3 and 1M HCl, dried (MgSO4), filtered, and concentrated to provide the desired product (5.85 g). MS (DCI) m/e 256, 258 (M+H)+; 273, 275 (M+NH4)+.
