Hydrochloride of 3-bromo-4-aminotoluene

The partially dried 3-bromo-4-acetaminotoluene is refluxed with 500 cc. of 95 per cent ethyl alcohol in a 3-I. round-bottom flask. To the boiling solution is added 500 cc. of concentrated hydrochloric acid and the refluxing is continued for three hours. During this time, crystals of the hydrochloride of 3-bromo-4-aminotoluene separate. The hot mixture is poured into a 2-I. beaker and cooled thoroughly in running water. The hydrochloride is filtered by suction and washed rapidly with two loo-cc. portions of chilled alcohol. The weight of the hydrochloride is 2501-300 g. (Note 4).
