Potassium carbonate (132.4 mg, 0.96 mmol) was added to a mixed solution of 4-[1,1,1,3,3,3-hexafluoro-2-(methoxymethyl)oxypropan-2-yl]-2-propylphenol (221.1 mg, 0.64 mmol) and 1,4-dibromobutane (1.38 g, 6.39 mmol) in N,N-dimethylformamide (20 mL), followed by stirring overnight. Water was added to the reaction solution, followed by extraction with ethyl acetate. Then, the organic layer was washed with saturated saline, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel preparative thin-layer chromatography (hexane:ethyl acetate=10:1) to obtain 219.5 mg of the title compound (yield: 71%) as a colorless oil.
