To a solution of (5,5-dimethyltetrahydrofuran-3-yl)methanol (2.00 g) in dichloromethane (30 ml) were added carbon tetrabromide (6.10 g) and triphenylphosphine (4.80 g) at room temperature. The reaction mixture was stirred at room temperature for 20 hr, and extracted with diethyl ether. The extract was dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/petroleum ether) to give the title compound (2.40 g) as a colorless oil.
