Title (EN) PROCESS FOR THE PREPARATION OF REGORAFENIB AND ITS CRYSTALLINE FORMS
(FR) PROCÉDÉ POUR LA PRÉPARATION DU RÉGORAFÉNIB ET SES FORMES CRISTALLINES
Abstract:
(EN) The present invention relates to a process for the preparation of 4-[4-({[4-chloro-3-(trifluoromethyl)phenyl]carbamoyl}amino)-3-fluorophenoxy]-N-methylpyridine-2-carboxamide or Regorafenib (I): Formula (I). The present invention further relates to a process for the purification of 4-[4-({[4-chloro-3-(trifluoromethyl) phenyl] carbamoyl} amino)-3-fluorophenoxy]-N-methylpyridine-2- carboxamide or Regorafenib (I) to provide highly pure material. The present invention further relates to a process for the preparation stable crystalline material of 4-[4-({[4-chloro-3-(trifluoromethyl)phenyl]carbamoyl}amino)-3-fluorophenoxy]- N-methyl pyridine-2-carboxamide or Regorafenib (I) useful in the preparation of pharmaceutical compositions for the treatment of cancer.
(FR) La présente invention concerne un procédé pour la préparation de 4-[4-({[4-chloro-3- (trifluorométhyle)phényl]carbamoyl}amino)-3-fluorophénoxy]-N-méthylpyridine -2-carboxamide ou du régorafénib (I) : Formule (I). La présente invention concerne en outre un procédé pour la purification de 4-[4-({ [4-chloro-3-(trifluorométhyle)phényl]carbamoyl}amino)-3-fluorophénoxy]-N-méthylpyridine-2-carboxamide ou du régorafénib (I) pour fournir un matériau hautement pur. La présente invention concerne en outre un procédé pour la préparation d'un matériau cristallin stable de 4-[4-({[4-chloro-3-(trifluorométhyl)phényl]carbamoyl}amino) -3-fluorophénoxy]-N-méthylpyridine-2-carboxamide ou de régorafénib (I) utiles dans la préparation de compositions pharmaceutiques pour le traitement du cancer.
