N-((1-Benzylpyrrolidin-3-yl)methyl)cyclopropanamine → N-(Pyrrolidin-3-ylmethyl)cyclopropanamine

Participants

Reaction Steps

A mixture of 13.6 g (59.0 mmol) of 1-(phenylmethyl)-N-cyclopropyl-3-pyrrolidinemethanamine, 0.5 g of 20% palladium on carbon and 140 ml of methanol was shaken in an atmosphere of hydrogen at about 50 psi and room temperature for 24 hours. The catalyst was removed by filtering through Celite, the filtrate concentrated and distilled in vacuo to give 6.3 g of N-cyclopropyl-3-pyrrolidinemethanamine, bp 88°-90° C. (13 mm).
