실험 절차

The starting material is prepared as follows: To the ice cooled stirred solution of 62.5 ml of 1,3-diaminopropane in 100 ml of ethanol, 30 g of 1-benzyl-4-piperidone are added dropwise. The mixture is hydrogenated over 2 g of pre-reduced platinum oxide at 50° and 2.7 atm. for 9 hours. After theoretical hydrogen-uptake the catalyst is filtered off, the filtrate evaporated, the residue distilled and the fraction boiling at 145°-160°/0.2 mmHg collected, to yield the 4-(3-aminopropylamino)-1-benzylpiperidine.
