Title (EN) PROCESS FOR PREPARING HALOGENATED IMIDAZOPYRIDINE DERIVATIVES
(FR) PROCÉDÉ DE PRODUCTION DE DÉRIVÉS D'IMIDAZOPYRIDINES HALOGÉNÉS
(DE) VERFAHREN ZUR HERSTELLUNG HALOGENIERTER IMIDAZOPYRIDINDERIVATE
Abstract:
(EN) The present invention relates to a process for preparing halogenated imidazopyridine derivatives of the formula (II) starting from compounds of the formula (I) via intermediates of the formula (IVa) or (IVb) in which the radicals Q, Z, R1, R3, R4, Rc, A1 and A2 have the abovementioned meanings. The invention furthermore relates to such halogenated imidazopyridine derivatives and to intermediates and reaction products from compounds of the formula (II) to give compounds of the formula (III) in which the above structural units have the abovementioned meanings.
(FR) L'invention concerne un procédé pour produire des dérivés d'imidazopyridines halogénés de formule (II) à partir de composés de formule (I) au moyen de produits intermédiaires de formule (IVa) ou (IVb) dans lesquelles les groupes Q, Z, R, R3, R4, Rc, A1 et A2 ont la signification figurant dans la description. Cette invention concerne en outre de tels dérivés d'imidazopyridines halogénés, ainsi que des produits intermédiaires et les produits de réaction de composés de formule (II) pour obtenir des composés de formule (III) dans laquelle les éléments structuraux indiqués ont la signification figurant dans la description.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von halogenierten Imidazopyridinderivaten der Formel (II) ausgehend von Verbindungen der Formel (I) über Zwischenstufen der Formel (IVa) oder (IVb) in welchen die Reste Q, Z, R1, R3, R4, Rc, A1 und A2 die genannten Bedeutungen haben. Ferner betrifft die Erfindung derartige halogenierte Imidazopyridinderivate, sowie Zwischenstufen und die Umsetzungsprodukte von Verbindungen der Formel (II) zu Verbindungen der Formel (III) in welcher die angegebenen Strukturelemente die genannten Bedeutungen haben.
