実験手順

Lithium aluminium hydride (68.3 mg, 1.80 mmols) was added to a diethyl ether (10 ml) solution of methyl 4-[4-(4,5,6,7-tetramethoxyindan-2-yl)butoxy]benzoate (400 mg, 0.900 mmols), with cooling with ice, then the mixture was warmed to room temperature, and stirred for 1 hour. 1N hydrochloric acid was added to the reaction mixture with cooling with ice, which was then extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, and then dried. The solvent was evaporated out in vacuo to obtain the entitled compound (370 mg) as an oil.
