反应详情

To a reaction vessel containing methyl 5-methylnicotinate (Alfa Aesar, 1 g, 6.62 mmol) in EtOH (12.03 mL) was added AcOH (1.203 mL). The reaction vessel was purged with nitrogen gas (3×) and 10 weight percent palladium on carbon (0.5 g, 4.70 mmol) was added. The reaction vessel was then purged with hydrogen (balloon, 1 atm) (3×) and maintained under hydrogen while stirring. After 48 hours, the reaction was filtered over Celite® brand filter aid and concentrated under reduced pressure to give methyl 5-methylpiperidine-3-carboxylate. ESI-MS M+H 158.0.
