4-Hydroxy-3-(trifluoromethyl)benzoic acid (2 g, 9.7 mmol) was dissolved in methanol (40 mL) and 12N HCl (10 drops) was added thereto. The reaction mixture was stirred at 90° C. for 48 hours, cooled to room temperature and concentrated, and then ethyl acetate (100 mL) was added thereto. The reaction mixture was washed with sat. NaHCO3 Solution, and the organic layer was dried with Na2SO4, filtered and concentrated to obtain the title compound (2.07 g, 91%) without further purification.
