Reaction Steps

A mixture of 4-hydroxybenzotrifluoride (2.08 g, 12.83 mmol), 2-(2-bromoethoxy)tetrahydropyran (3 g, 14.11 mmol), potassium carbonate (1.95 g, 14.11 mmol), and sodium iodide (2 g, 13.47 mmol) in DMF (15 ml) was stirred at 100° C. for 3 hours. The reaction mixture was allowed to return to room temperature, poured into water, and extracted with ethyl acetate twice. The extract was washed with water twice and brine, and dried over magnesium sulfate. After filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (n-hexane/ethyl acetate=1/1) to afford 2-[2-(4-trifluoromethylphenoxy)ethoxy]tetrahydropyran (2.47 g, yield 66%) as a colorless oil.
