反応手順
2.9 Kg. of 1-[3-(p-tert.-butyl-phenyl)-2-methyl-1-propenyl]-piperidine are taken up in 1.4 liters of toluene, treated under an atmosphere of nitrogen with 144.8 g. of 5% palladium/carbon and hydrogenated at 35° C. until the hydrogen uptake has been completed. The catalyst is removed by filtration, the toluene is evaporated in vacuo and the residue is distilled. There is obtained pure 1-[3-(p-tert.-butyl-phenyl)-2-methyl-propyl]-piperidine, having a boiling point of 125° C./0.045 Torr.
