Participants

Reaction Steps

830 g of 3-[1-methylcyclohexen-4-yl]-butyraldehyde were dissolved in 800 ml of liquid ammonia in a stirrer autoclave and hydrogenated over 50 g of Raney nickel iron at 90° C. and a hydrogen pressure of 100 bar. After evaporation of the solvent, the mixture was filtered from the catalyst and distilled under vacuum. 720 g (86%) of 3-(1-methylcyclohexen-4-yl)-butylamine, b.p.10 120° C. were obtained.
