Procedure

2-Trifluoromethyl-phenol (2.98 g, 18.3 mmol) was dissolved in 12 mL TFA and t-butanol (1.43 g, 19.3 mmol) and H2SO4 (0.24 mL) were added. The reaction was stirred at rt for 48 hrs, after which water was added and the compound was extracted into DCM. The organic layer was dried over MgSO4 and concentrated in vacuo. The residue was purified by column chromatography (2/1 Hex/EtOAc) to yield 2.01 g of the target compound.
