Reaction Steps

To a solution of 4-bromo-2,6-dimethylaniline (100.0 g) in tetrahydrofuran (400 mL) was added triethylamine (60.7 g) and 2-bromopropionyl bromide (129.5 g) under ice-cooling. The mixture was stirred at room temperature for 1 hour and cooled in an ice-cooling bath. To the reaction mixture was added a sodium hydrogencarbonate aqueous solution and the mixture was stirred at room temperature for 30 minutes. The precipitate was collected by filtration, washed with water and diethyl ether, and dried to give 2-bromo-N-(4-bromo-2,6-dimethylphenyl)propionamide (151.2 g).
