CA 2741332

The invention relates to (pyrrolidin-2-yl)phenyl derivatives having the general Formula (I), wherein R1 is (C1-4)alkyl, halo(C1-4)alkyl, (C1-4)alkyloxy, or halo(C1-4)alkyloxy; R2 is H, (C1-4)alkyl, halo(C1-4)alkyl, (C1-4)alkyloxy, halo(C1-4)alkyloxy or halogen; R3 is H, (C1-4)alkyl or halo(C1-4)alkyl; R4 is H, (C1-4)alkyl or halo(C1-4)alkyl; R5 is H, (C1-4)alkyl or halo(C1-4)alkyl; or R4 and R5, when bonded to the same carbon atom, can together with the carbon atom form a spiro(C3-6)cycloalkyl group, optionally substituted with halogen; R6 is H, (C1-4)alkyl, halo(C1-4)alkyl, (C1- 4)alkyloxy, halo(C1-4)alkyloxy or halogen; or a pharmaceutically acceptable salt thereof, to pharmaceutical compositions comprising the same, as well as to the use of these (pyrrolidin-2-yl)phenyl derivatives for the treatment of pain, such as neuropathic pain or inflammatory pain.

L'invention porte sur des dérivés (pyrrolidin-2-yl)phényliques répondant à la formule générale (I), dans laquelle R1 représente alkyle en C1-4, halo(alkyle en C1-4), alkyloxy en C1-4, ou halo(alkyloxy en C1-4) ; R2 représente H, alkyle en C1-4, halo(alkyle en C1-4), alkyloxy en C1-4, halo(alkyloxy en C1-4) ou halogène ; R3 représente H, alkyle en C1-4 ou halo(alkyle en C1-4) ; R4 représente H, alkyle en C1-4 ou halo(alkyle en C1-4) ; R5 représente H, alkyle en C1-4 ou halo(alkyle en C1-4) ; ou R4 et R5, lorsqu'ils sont liés au même atome de carbone, peuvent conjointement avec l'atome de carbone former un groupe spirocycloalkyle en C3-6, facultativement substitué par halogène ; R6 représente H, alkyle en C1-4, halo(alkyle en C1-4), alkyloxy en C1-4, halo(alkyloxy en C1-4) ou halogène ; ou un sel pharmaceutiquement acceptable de ceux-ci, sur des compositions pharmaceutiques les comprenant, ainsi que sur l'utilisation de ces dérivés (pyrrolidin-2-yl)phényliques pour le traitement de la douleur, telle qu'une douleur neuropathique ou une douleur inflammatoire.
