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.
一种生产 N-取代的
吡啶甲酰胺或
硫代甲酰胺的工艺,包括使取代或未取代的
吡啶金属化合物与取代的
异氰酸酯或异
硫氰酸酯反应,得到其加成反应产物,然后用质子取代所述加成反应产物中的
