Methylamine → 1-Benzyl-N-methylpiperidin-3-amine

Participants

Reaction Steps

A suspension of 0.30 g. of platinum oxide in 20 ml. of absolute ethanol was shaken under 35 psi of hydrogen for 1 hour. To this was added a solution of 12.44 g. (65.9 mmoles) of 1-benzyl-3-piperidone and 4.1 g. (132 mmoles) of methylamine in 40 ml. of absolute ethanol. The mixture was then shaken under ca. 50 psi of hydrogen until uptake ceased. Filtration and evaporation afforded 1-benzyl-3-methylaminopiperidine.
