실험 절차
3-Acetyl-2-(N,N-diethylaminomethyl)-4-(3,4-dimethoxyphenyl)-6,7-dimethoxyquinoline (0.5 g) was added to an ice-cooled suspension of lithium aluminum hydride (0.045 g) in tetrahydrofuran (10 ml). The mixture was stirred at room temperature for 20 minutes. Then, water (0.3 ml) was added, and the insoluble material was filtered off. The filtrate was concentrated under reduced pressure. The residue was subjected to column chromatography on silica gel. The fractions eluted with chloroform-ethanol (20:1, v/v) gave 2-(N,N-diethylaminomethyl)-4-(3,4-dimethoxyphenyl)-3-(1-hydroxyethyl)-6,7-dimethoxyquinoline (0.23 g, 45%). This compound was recrystallized from ethyl acetate-hexane to give colorless prisms, mp. 144°-145° C.
