A synergistic Pd–C catalytic hydrogenation of 4-pyridinecarboxamides straightforward to 4-piperidinecarboxamide hydrochlorides was developed in the presence of ClCH2CHCl2. It provided a novel strategy for highlyefficient hydrogenation of pyridine nuclear by using low-cost Pd–C catalyst undermildconditions.
