Versuchsvorschrift

A mixture of 14.0 g (60.0 mmole) of 1-(phenylmethyl)-N-propyl-3-pyrrolidinemethanamine, 1.0 g of 20% palladium on carbon and 140 ml of methanol was shaken in an atmosphere of hydrogen at about 4.5×105Pa and room temperature for 24 hours. The catalyst was removed by filtering through Celite, the filtrate concentrated and distilled in vacuo to give 7.1 g of N-propyl-3-pyrrolidinemethanamine, bp 49°-50° C./0.25 mm.
