4-Bromomethylbenzoic acid

6232-88-8

In a 100 mL round-bottomed flask, 40 mL of carbon tetrachloride was added as solvent, 3.00 g of p-methylbenzoic acid as starting material, 4.00 g of N-bromosuccinimide (NBS) as bromination reagent, and 0.1 g of azobisisobutyronitrile (AIBN) as initiator. The reaction mixture was stirred and refluxed at 90 °C and the reaction process was monitored by thin layer chromatography (TLC). Upon completion of the reaction, the mixture was cooled to room temperature followed by filtration. The filter cake was washed with warm water to remove the succinimide by-products generated in the reaction. After drying, 4.02 g of p-bromomethylbenzoic acid was obtained with a melting point of 231-232°C in 84% yield.
