How is 3-bromo-5-(trifluoromethyl)benzoic acid (CAS: 328-67-6) typically synthesized?

3-Bromo-5-(trifluoromethyl)benzoic acid is typically synthesized through a multi-step process. Starting from benzoic acid, a trifluoromethyl group is introduced using an appropriate trifluoromethylating agent such as triflic anhydride. The resulting intermediate is then brominated using N-bromosuccinimide (NBS) or similar reagents. The reaction conditions include the use of a radical initiator and careful control of temperature to achieve a high yield and good selectivity.
