Title (EN) PROCESS FOR PREPARING HALOGENATED PYRIDINE DERIVATIVES
(FR) PROCÉDÉ DE PRODUCTION DE DÉRIVÉS HALOGÉNÉS DE LA PYRIDINE
(DE) VERFAHREN ZUR HERSTELLUNG HALOGENIERTER PYRIDINDERIVATE
Abstract:
(EN) The present invention relates to a method for preparing halogenated pyridine derivatives of formula (II) starting from compounds of formula (I) via intermediate stages of formula (IIIa) or (IIIb), in which the radicals Q and W independently of one another represent halogen, R2 represents halogen or -O-pivaloyl, and Y represents halogen, CO2R1 or NO2, in which R1 represents (C1-C6) alkyl or (C1-C6) haloalkyl.
(FR) L'invention concerne un procédé de production de dérivés halogénés de la pyridine représentés par la formule (II) à partir de composés de formule (I) en passant par des intermédiaires représentés par la formule (IIIa) ou (IIIb), formules dans lesquelles les restes Q et W représentent indépendamment l'un de l'autre halogène, R2 représente halogène ou un groupe -O-pivaloyle, Y représente halogène, CO2R1 ou NO2, R1 désignant un radical (C1-C6)-alkyle ou (C1-C6)-haloalkyle.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von halogenierten Pyridinderivaten der Formel (II) ausgehend von Verbindungen der Formel (I) über Zwischenstufen der Formel (IIIa) oder (IIIb), in welchen die Reste Q und W unabhängig voneinander für Halogen stehen, R2 für Halogen oder –O-Pivaloyl steht, und Y für Halogen, CO2R1 oder NO2 steht, wobei R1 für (C1-C6)-Alkyl oder (C1-C6)-Haloalkyl steht.
