Procedure
2,2,2-Trifluoroethyl triflate (1.02 g, 4.40 mmol) and potassium carbonate (1.10 g, 1.01 mmol) were added to a solution of 4-hydroxy-2,6-dimethylphenyl acetate (673 mg, 3.73 mmol) in 2-butanone (15 mL). The mixture was stirred at 70° C. for 72 hours, then cooled to room temperature and concentrated. The residue was partitioned between water and ethyl acetate. The organic layer was washed twice with water and brine and dried. The solvent was removed in vacuo and the residue purified on silica gel, eluting with 10% ethyl acetate in hexanes, to give 2,6-dimethyl-4-(2,2,2-trifluoroethoxy)phenyl acetate (733 mg, 75%).
