Versuchsvorschrift

To a solution of 4-amino-3-trifluoromethoxybenzoic acid (5 g, 22.6 mmoles) in acetic acid (50 mL), bromine(3.98 g, 24.9 mmoles) in acetic acid(10 mL) was added dropwise at room temperature. After the reaction mixture was kept stirring for one hour, water was added into the mixture. The solid was filtered and washed with water to give 4-amino-3-bromo-5-trifluoromethoxybenzoic acid (3.9 g, 54.9%).
