To a solution of 4-bromo-2-propyl-3-[(tetrahydro-2H-pyran-2-yloxy)methyl]phenol (972 mg, 2.95 mmol) in N,N-dimethylformamide (5 mL), sodium hydride (55% in oil, 257 mg, 5.90 mmol) and chloromethyl methyl ether (475 mg, 5.90 mmol) were added at 0° C. The mixture was stirred at room temperature for 2 hours. The reaction solution was added with water and extracted with ethyl acetate. Subsequently, the organic layer was washed with saturated saline, dried using anhydrous sodium sulfate, and concentrated under vacuum. The residue was purified by silica-gel column chromatography (hexane/ethyl acetate), and the title compound (910 mg, 83%) was obtained as colorless oil.
