実験手順

A mixture of 90 g (0.66 mole) of 2-propylphenol, 300 g (1.30 mole) of 1,5-dibromopentane, 120 g of anhydrous potassium carbonate, and 9 g of sodium iodide in 1.2 l of methyl ethyl ketone was stirred at reflux for two days. After cooling, the mixture was filtered to remove insolubles and the filtrate was concentrated in vacuo. The residue was distilled under vacuum to give 120 g of the title compound as an analytically pure oil, b.p. 123°-125° at 0.1 mm Hg.
