Lithium aluminum hydride (579 mg) was added to dry THF (40 mL) under an argon atmosphere and ice cooling, a solution of 5,6,7-trimethoxynaphthalene-2-carboxylic acid (4.0 g) in dry THF (40 mL) was then added dropwise thereto, and the mixture was stirred at room temperature for 4 hours. Ether (150 mL) was added to the reaction mixture, sodium sulfate decahydrate was added thereto, and the resultant mixture was stirred for 15 minutes. The reaction mixture was filtered, the filtrate was concentrated, and the residue was purified by column chromatography on silica gel (ethyl acetate:hexane=1:2) to obtain the title compound.
