A simple method for monobromination of aromatic amines predominantly or exclusively in the para-position is reported. 2,4,4,6-Tetrabromocyclohexa-2,5-dienone is used as the halogenating agent in dichloromethane or chloroform. Protection of the amino-group is not necessary and yields are generally higher than 90%.
