实验步骤: With external cooling, 7-[(diethylamino)methyl[-hexahydro-2H-azepin-2-one hydrochloride (10.0 g, 0.043 mol) is added in batches to a suspension of lithium aluminium hydride (1.9 g, 0.05 mol) in anhydrous tetrahydrofuran (500 ml) and the mixture is refluxed for 1 hour after the initially violent reaction has ended. The excess lithium aluminium hydride is decomposed by the dropwise addition of 20% sodium hydroxide solution. The tetrahydrofuran phase is separated off from the precipitate formed and concentrated in vacuo. The oily residue remaining is then distilled over caustic potash under water jet vacuum. A colorless oil (4.7 g) is obtained, boiling point 12 mm Hg 102°-105° C. the mixture is refluxed for 1 hour after the initially violent reaction The tetrahydrofuran phase is separated off from the precipitate formed concentrated in vacuo The oily residue remaining is then distilled over caustic potash under water jet vacuum
