Title
(EN) PROCESS FOR THE PREPARATION OF ANTI-MALARIAL DRUGS
(FR) PROCEDE DE PREPARATION DE MEDICAMENTS ANTI-PALUDIQUES
Abstract
(EN)
The invention relates to novel intermediates and processes for the preparation of quinoline compounds useful as anti-malarial drugs and novel intermediates useful in the process. A process for the preparation of a compound of formula (I) in which R1 is C1-6 alkyl; R2 and R3 are independently hydrogen, halogen, trifluoromethyl or C1-6 alkoxy; R4 is C1-6 alkyl; R5 is hydrogen or C1-6 alkyl; and R6 is nitro or amino which comprises reacting a compound of formula (II) in which R1, R4 and R5 are as defined in formula (I) and X is a leading group with a compound of formula (III).
(FR)
Cette invention concerne de nouveaux produits intermédiaires et des procédés de préparation de composés de quinoline utiles en qualité de médicaments anti-paludiques, ainsi que de nouveaux produits intermédiaires utilisés dans ce procédé. Cette invention concerne un procédé de préparation d'un composé de formule (I) où R1 représente alkyle C1-6; R2 et R3 représentent indépendamment hydrogène, halogène, trifluorométhyle ou alcoxy C1-6; R4 représente alkyle C1-6; R5 représente hydrogène ou alkyle C1-6; et R6 représente nitro ou amino. Ce procédé consiste à faire réagir un composé de formule (II) où R1, R4 et R5 sont tels que définis dans la formule (I) et X est un groupe partant, avec un composé de formule (III).
