Versuchsvorschrift

1.02 g (26.8 mmol) of lithium aluminum hydride was suspended in 100 ml of tetrahydrofuran, to which was added dropwise a solution of 10 ml tetrafuran containing 5.06 g (26.6 mmol) of methyl(indan-2-yl)acetate under ice-cooling. After completion of the addition, stirring was continued for 1 hour, during which 1 ml water, 1 ml of 15% sodium hydroxide and 3 ml water were added dropwise in this order for decomposing the excessive reducing agent. The solid matter was removed by filtration, the filtrate was condensed and the residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:4) to obtain 4.30 g of a colorless oil. Yield: 100%
