Reaction Steps
30 g of N-butyryl-o-toluidine and 150 g of glacial acetic acid were initially charged at 30° C. A solution of 33 g of bromine in 66 g of glacial acetic acid was added with stirring and then stirring was continued at from 25 to 30° C. for 1 hour. 300 ml of water were then added to the reaction mixture which, after continued stirring for a short time, was filtered, the crystals were washed with water and dried under reduced pressure. 42.5 g (98% yield) of N-(4-bromo-2-methylphenyl)butanamide were obtained in 99.4% purity.
