| Two routes |

Two routes for the synthesis of cis-N-protected-3-methyla mino- 4-methylpiperidine (3) were examined: a route hinging on the electrochemical oxidation of carbamate 1 to install a ketone at the 3 position of the piperidine followed by reductive amination (disconnection A), and a route involving the hydrogenation of an appropriately functionalized pyridine (disconnection B). While both routes to the desired compound were ultimately successful, the pyridine hydrogenation approach proved to be more amenable to kilogram-scale preparations due to the crystallinity and purity of intermediates in that route. cuckold video
