5 g of Ru/C (5%) are added to a solution comprising 20.0 g (0.113 mol) of 2-(1,3-dimethylbutyl)aniline in 300 ml of tetrahydrofuran, and the mixture is hydrogenated with 100 bar of hydrogen at 120° C. for 24 hours. After cooling to room temperature, the catalyst is filtered off through Celite 545 and the product is concentrated under reduced pressure. This gives 19.1 g (92.4% of theory) of 2-(1,3-dimethylbutyl)cyclohexanamine having a purity of 100% according to HPLC and a log P (pH 2.3) of 4.07.
