Title
(DE) VERFAHREN ZUR HERSTELLUNG VON PYRIDINCARBOXAMIDEN UND THIOCARBOXAMIDEN
(EN) PROCESS FOR PRODUCING PYRIDINECARBOXAMIDES OR THIOCARBOXAMIDES
(FR) PROCEDE DE PRODUCTION DE PYRIDINECARBOXAMIDES OU DE THIOCARBOXAMIDES
Abstract
(EN)
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.

(FR)
Ce procédé, qui permet de produire des pyridinecarboxamides ou des thiocarboxamides N-substitués, consiste à soumettre un composé métallique, à base d'une pyridine éventuellement substituée, à une réaction d'addition avec un isocyanate ou un thioisocyanate substitué puis à remplacer le métal par un proton. Il s'applique même à des composés comprenant des substituants susceptibles de s'oxyder et se révèle donc avantageux sur le plan industriel.
