Procedure: 49.85 g (0.38 mol) of 3-[1,3]-dioxolan-2-yl-propylamine and 43.34 g (0.646 mol) of crotono-nitrile are combined in a 200 ml round-bottomed flask and heated at 100° C. for 72 hours. After cooling, the brown mass is diluted with ethyl acetate and washed with water. The organic phase is dried over calcium carbonate and purified by filtration on silica gel (eluent: ethyl acetate). Evaporation of the solvent gives 69.8 g of 3-(3-[1,3]-dioxolan-2-yl-propylamino)butyronitrile as a reddish liquid which is used without further purification in the next stage. After cooling washed with water The organic phase is dried over calcium carbonate purified by filtration on silica gel (eluent: ethyl acetate) Evaporation of the solvent

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. Added dropwise to this suspension The mixture is subsequently heated at reflux for 2.5 hours After cooling The mixture is then filtered the filtrate is dried over calcium chloride concentrated The orange oil obtained is subsequently distilled under reduced pressure (overhead temperature=46° C., p=0.016 mbar)
