실험 절차

A solution of 4-(3-benzyloxyphenyl)butyric acid (22.0 g) in tetrahydrofuran (150 ml) was added dropwise to a suspension of lithium aluminum hydride (6.18 g) in tetrahydrofuran (150 ml) at 0° C. and then stirred for one hour at room temperature. The reaction mixture was quenched with H2O, acidified with 1N-hydrochloric acid, and extracted with ethyl acetate. The ethyl acetate layer was washed with 1N-hydrochloric acid, saturated aqueous sodium bicarbonate and water, dried (MgSO4), and concentrated under reduced pressure to give 4-(3-benzyloxyphenyl)butanol (20.5 g, 99%). Oily substance.
