実験手順
A mixture of 4-carbamoyl-1-phenylpyridinium chloride (13 g), 10% palladium-on-carbon catalyst (260 mg) and ethanol (250 ml) was hydrogenated at ambient temperature and pressure for 2 days. The solution was filtered (Celite) and the filtrate was concentrated to approximately 50 ml. This solution was cooled and the solid precipitate collected by filtration to give 1-phenylpiperidine-4-carboxamide (5.99 g).
