To a solution of methyl 2-[(E)-2-phenylvinyl]isonicotinate in acetic acid was added platinum oxide, followed by stirring at room temperature for 8 hours under a hydrogen atmosphere of 3 atm. The reaction mixture was filtered through Celite, and the filtrate was then concentrated under reduced pressure. To the residue were added an aqueous Na2CO3 solution, and the EtOAc was extracted. The organic layer was dried over MgSO4 and then concentrated under reduced pressure to obtain methyl 2-(2-phenylethyl)piperidine-4-carboxylate as a colorless oil.
