How is 5-Bromo-2-fluorobenzoic acid (CAS: 146328-85-0) typically synthesized?

5-Bromo-2-fluorobenzoic acid is typically synthesized by the bromination of 2-fluorobenzoic acid using N-bromosuccinimide (NBS) in the presence of a radical initiator like benzoyl peroxide. The reaction involves the addition of bromine to the acid molecule. This method provides good yields and selectivity, making it a common approach in the laboratory for producing this compound.
