HCID 13574688gamma,4-Dimethylcyclohexene-1-propan-1-amineYield 86%

Procedure

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