tert-Butyl [3-chloro-4-(trifluoromethyl)phenoxy]acetate (1.2 g, 3.8 mmol) was added trifluoroacetic acid (TFA) (3 ml). The mixture was stirred for 5 hours at ambient temperature. The solvent was removed under reduced pressure to give the residue, which was applied to a recrystallization from hexane-methylene dichloride to furnish 251 mg (80% yield) of the title compound as a brown solid.
