Procedure: 0.289 g of Ru/C (5%) are added to a solution comprising 3.00 g (17.31 mmol) 2-[1,1′-Bi(cyclopropyl)-2-yl]anilin in 20 ml of tetrahydrofuran, and the mixture is hydrogenated with 100 bar of hydrogen at 120° C. for 20 hours. After cooling to room temperature, the catalyst is filtered off through Celite 545 and the product is concentrated under reduced pressure. This gives 3.01 g (96%) of 2-[1,1′-Bi(cyclopropyl)-2-yl]cyclohexanamine having a purity of 96% according to MSD-HPLC. the catalyst is filtered off through Celite 545 the product is concentrated under reduced pressure

Procedure: 1 g of benzyl(2-bicyclopropyl-2-yl-phenyl)amine (3.8 mmol, trans/cis ratio of about 3:1) is dissolved in 15 ml of absolute tetrahydrofuran. Then 50 mg of Pd (5%) on activated carbon are added. Hydrogenation is then carried out, with stirring, for 1 hour at room temperature. After completion of the reaction, the catalyst is filtered off and the solvent is removed using a water jet vacuum. The product is purified by chromatography on silica gel (eluant:ethyl acetate/hexane 1/15). 0.61 g of 2-bicyclopropyl-2-ylphenylamine (92% of theory) is obtained in the form of a brownish liquid (trans/cis ratio of about 3:1). After completion of the reaction the catalyst is filtered off the solvent is removed The product is purified by chromatography on silica gel (eluant:ethyl acetate/hexane 1/15)

Procedure: In a hydrogenation reactor, 1 g of 2-(2-nitrophenyl)-bicyclopropane (4.9 mmol, trans:cis ratio: 4.1:1), dissolved in 20 ml of ethanol, is hydrogenated at ambient temperature using 0.1 g of 5% platinum-carbon catalyst. After 2.5 hours and after 101% of the amount of hydrogen theoretically required for the reduction has been taken up, the reaction is stopped. Following filtration of the reaction mixture, the solvent is removed by concentration by evaporation. 0.87 g of 2-(2-aminophenyl)-bicyclopropane (100% of theory) is obtained in the form of a brownish liquid (trans:cis ratio: 4.4:1). is hydrogenated at ambient temperature filtration of the reaction mixture the solvent is removed by concentration by evaporation
