Patent

CA 2583918

The present invention relates to aromatic compounds of the formula (I) wherein Ar is phenyl or an aromatic 5- or 6-membered C-bound heteroaromatic radical, wherein Ar may carry 1 radical Ra and wherein Ar may also carry 1 or 2 radicals Rb; X is N or CH; E is CR6R7 or NR3;R1 is C1-C4-alkyl, C3-C4- cycloalkyl, C3-C4-cycloalkylmethyl, C3-C4-alkenyl, fluorinated Cl-C4~-alkyl, fluorinated C3-C4-cycloalkyl, fluorinated C3-C4-cycloalkylmethyl, fluorinated C3-C4~-alkenyl, formyl or C1-C3-alkylcarbonyl; R1a is H, C1-C4-alkyl, C3-C4- cycloalkyl, C3-C4-cycloalkylmethyl, C3-C4-alkenyl, fluorinated C1-~C4-alkyl, fluorinated C3-C4-cycloalkyl, fluorinated C3-C4-cycloalkylmethyl, fluorinated C3~-C4-alkenyl, or R1a and R2 together are (CH2)n with n being 2, 3 or 4, or R1a and R2a together are (CH2)n with n being 2, 3 or 4; R2 and R2a are independently of each other H, C1-C4-alkyl or fluorinated C1-C4-alkyl or R2a and R2 together are (CH2)m with m being 1, 2, 3, 4 or 5; R3 is H or C1-C4- alkyl; R6, R7 independently of each other are selected from H, fluorine, C1-C4- alkyl and fluorinated C1-C4-alkyl or together form a moiety (CH2)p with p being 2, 3, 4 or 5; and the physiologically tolerated acid addition salts thereof. The invention also relates to the use of a compound of the formula (I) or a pharmaceutically acceptable salt thereof for preparing a pharmaceutical composition for the treatment of a medical disorder susceptible to treatment with a dopamine D3 receptor ligand.

L'invention concerne des composés aromatiques représentés par la formule (I) et des sels d'addition acides de ces composés physiologiquement tolérés. Dans cette formule, Ar représente phényle ou un radical hétéroaromatique à liaison C à 5 ou 6 éléments aromatiques, Ar pouvant porter un 1 radical Ra et également 1 ou 2 radicaux Rb; X représente N ou CH; E représente CR6R7 ou NR 3; R1 représente C1-C4-alkyle, C3-C4-cycloalkyle, C3-C4-cycloalkylméthyle, C3-C4-alcényle, C1-C4-alkyle fluoré, C3-C4-cycloalkyle fluoré, C3-C4-cycloalkylméthyle fluoré, C3-C4-alcényle fluoré, formyle ou C1-C3-alkylcarbonyle; R1a représente H, C1-C4-alkyle, C3-C4-cycloalkyle, C3-C4-cycloalkylméthyle, C3-C4-alcényle, C1-C4-alkyle fluoré, C3-C4-cycloalkyle fluoré, C3-C4-cycloalkylméthyle fluoré, C3-C4-alcényle fluoré, ou R1a et R2 représentent ensemble (CH2)n, n étant égal à 2 ou 3 ou 4; R2 et R2a représentent chacun indépendamment l'un de l'autre H, C1-C4-alkyle, C1-C4-alkyle fluoré, ou R2a et R2 représentent ensemble(CH2)m, m étant égal à 1, 2, 3, 4 ou 5; R3 représente H ou C1-C4-alkyle; R6, R7 sont indépendamment l'un de l'autre sélectionnés à partir de H, fluore, C1-C4-alkyle et C1-C4-alkyle fluoré ou forment ensemble une fraction (CH2)p, p étant égal à 2 ou 3, 4 ou 5. L'invention concerne également l'utilisation d'un composé représenté par la formule (I) ou d'un sel pharmaceutiquement acceptable de celui-ci permettant de préparer une composition pharmaceutique destinée à traiter un trouble médical susceptible d'être traiter au moyen d'un ligand du récepteur D3 de la dopamine.
