実験手順

A solution of 30 g of 5,6-methylenedioxyindan-1-one in 120 ml of tetrahydrofuran was added dropwise to a suspension of 2.4 g of lithium aluminum hydride in 160 ml of anhydrous tetrahydrofuran under cooling with ice. The mixture was stirred at room temperature overnight. 2.4 ml of water, then 2.4 ml of 15% aqueous sodium hydroxide solution and finally 7.2 ml of water were added thereto and insoluble substances were filtered off. The filtrate was distilled and the residue was washed with diisopropyl ether to obtain 24.3 g of the intended compound in the form of faint brown crystals.
