10% Pd/C (590 mg) was added to 3-benzyloxy-4-trifluoromethyl-benzoic acid in a methanol-ethyl acetate mixed solvent (1:1), and the mixture was stirred at room temperature for two days in a hydrogen atmosphere. The reaction solution was filtered through celite, and the filtrate was then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (n-hexane-ethyl acetate) to give 3-hydroxy-4-trifluoromethyl-benzoic acid (582 mg, 86%).
