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金属。根据本发明的工艺甚至可以应用于具有易氧化取代基的化合物,因此在工业上非常有用。
