How is 4-(Acetoxymethyl)-3-bromobenzoic acid (CAS: 90772-73-9) typically synthesized?

4-(Acetoxymethyl)-3-bromobenzoic acid can be synthesized through a multi-step reaction starting from 3-bromobenzoic acid. The key steps include esterification of the carboxylic acid group to form the acetate ester, followed by bromination of the hydroxyl group at the methyl position. This process typically involves the use of acetic anhydride and a suitable base as a catalyst.
