実験手順
50.1 g (1.32 mol) of lithium aluminium hydride are suspended in 500 ml of ether. Added dropwise to this suspension is a solution of 111.9 g (0.88 mol) of 3-[1,3]-dioxolan-2-yl-propionitrile. The mixture is subsequently heated at reflux for 2.5 hours. After cooling, 50 g of water, 50 g of 10% strength sodium hydroxide solution and a further 150 g of water are added. The mixture is then filtered and the filtrate is dried over calcium chloride and concentrated. The orange oil obtained is subsequently distilled under reduced pressure (overhead temperature=46° C., p=0.016 mbar). This gives 68.4 g of 3-[1,3]-dioxolan-2-yl-propylamine.
