Reaction Steps

A solution of 1-(2-tetrahydrofurylmethyl)piperid-4-one oxime (42.5 g; 0.22 moles) in anhydrous tetrahydrofuran (700 ml) was added dropwise to a suspension of lithium aluminium hydride (24.4 g; 0.64 moles) in anhydrous tetrahydrofuran (300 ml). The reaction mixture was left with stirring at room temperature overnight and then, water (24.5 ml), 4N sodium hydroxide aqueous solution (24.5 ml) and water (73.5 ml) were successively added, filtered, the filtrates dried (Na2SO4) and brought to dryness in vacuo. The resulting oil (28 g) was distilled to give 1-(2-tetrahydrofurylmethyl)-4-aminopiperidine, boiling point 94°-98° C./0.2 mm Hg.
