To a tetrahydrofuran (1 ml) solution of ethyl [3,5-difluoro-4-(2,2,2-trifluoro-1,1-dimethylethyl)phenoxy]acetate (267 mg, 0.82 mmol) and methanol (1.5 ml) was added 2 N sodium hydroxide aqueous solution (1 ml) and the mixture was stirred at 60° C. for 30 minutes. After the reaction was complete, the basic mixture was acidified with 2 N hydrochloride aqueous solution and the product was extracted with ethyl acetate which was dried over sodium sulfate. The organic layer was filtered and concentrated to give 242 mg (99% yield) of the title compound as a brown solid.
