Procedure

A mixture of 1.25 g (5.72 mmol) of N,N-dimethyl-1-(phenylmethyl)-3-pyrrolidinemethanamine, 100 ml of methyl alcohol, 0.2 g of 20% palladium on carbon and hydrogen were shaken at a pressure of 55.1 psi. After 16.8 hours the catalyst was filtered and the filtrate evaporated under reduced pressure. The residue was bulb to bulb distilled yielding 0.71 g (97%) N,N-dimethyl-3-pyrrolidinemethanamine as a clear yellow oil.
