Procedure

4-hydroxy-2-trifluoromethyl-benzoic acid (5.0 g, 24.0 mmol) was dissolved in MeOH (50 mL) and a catalytic quantity of sulfuric acid was added. The mixture was refluxed overnight, after which the solvent was evaporated under reduced pressure; the crude was dissolved in DCM and washed with saturated NaHCO3. The organic phase was dried and evaporated under reduced pressure, and the product was used without further purification.
