Reaction Steps
A solution of 179 g of bromine in 120 ml of acetic acid was added at less than 40° C. over 45 minutes under an inert atmosphere to a mixture of 120 g of N-methyl-aniline and 600 ml of acetic acid and the mixture was stirred for 75 minutes and then was cooled to room temperature and poured into a mixture of ice and water. The pH of the mixture was adjusted to 10 by addition of sodium hydroxide and the mixture was extracted with methylene chloride. The organic phase was washed with aqueous saturated sodium chloride solution, dried and evaporated to dryness under reduced pressure to obtain 213 g of N-methyl-4-bromo-aniline.
