Procedure

5.1 g of 8-(3-hydroxypropyl)-1-methoxymethoxy naphthalene was dissolved in 40 ml of N,N-dimethyl formamide, to which 1.4 g of 55% sodium hydride was added under ice cooling. Then, 1.93 ml of methyl iodide was added and stirred at a room temperature for 2 hours. After adding water to the reaction solution and extracting with ethyl acetate, the organic layer was washed with water and then with a saturated aqueous solution of sodium chloride successively and then dried over magnesium sulfate. After distilling off the solvent, when it was purified on silica gel column chromatography (10% ethyl acetate-hexane), 5.3 g of the above-captioned compound was obtained as a colorless oily product.
