2-Bromo-4-methylaniline Use and Manufacturing

Methods of Manufacturing

P-toluidine and glacial acetic acid are heated and refluxed for 2h to convert to N-acetyl-p-toluidine, cooled to 45°C, bromine is added dropwise, and the bromination reaction is controlled at 50-55°C. The reactant was poured into an aqueous solution of sodium sulfite to precipitate 3-bromo-4-acetamidotoluene. Then it is hydrolyzed with concentrated hydrochloric acid, and the resulting hydrochloride is reacted with sodium hydroxide solution to obtain free 2-bromo-4-methylaniline. The yield is 51-57%.

Uses

Organic synthesis intermediate.
