A process for producing N-substituted pyridine carboxamide or thiocarboxamide, comprising reacting a substituted or unsubstituted pyridine metal compound with substituted isocyanate or isothiocyanate to obtain an addition reaction product thereof, and then substituting the metal of said addition reaction product with a proton. The process according to the present invention can be applied even to compounds having an oxidation-susceptible substituent group and, therefore, industrially useful.
