Patent

CA 2583967

The present invention relates to 6-amino(aza)indane compound 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 I or 2 radicals Rb; X is N or CH; E is CR6R7 or NR 3; R1 is 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, formyl or C1-C3-alkylcarbonyl; R1a is H or R1a and R2 or R1a and R2a together are (CH2)n with n being 1, 2, 3 or 4; R2 and R2a each independently are H, CH3, CH2F, CHF2 or CF3; R3 is H or C,-C4-alkyl; and the physiologically tolerated acid addition salts of these compounds. The invention also relates to pharmaceutical compositions comprising at least one compound of the formula (I) or a pharmaceutically acceptable salt thereof and to a method for treating a medical disorder susceptible to treatment with a dopamine D3 receptor ligand, said method comprising administering an effective amount of at least one compound of the formula (I) or a pharmaceutically acceptable salt thereof.

L invention concerne un composé de 6-amino(aza)indane représenté par la formule (I) et des sels d'addition acides de ce composé 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 ou R1a et R2 ou R1a et R2a ensemble représentent (CH2)n, n étant égal à 1, 2, 3 ou 4; R2 et R2a représentent chacun indépendamment H, CH3, CH2F, CHF2 ou CF3; R3 représente H ou C,-C4-alkyle. L'invention concerne également des compositions pharmaceutiques comprenant au moins un composé représenté par la formule (I) ou un sel pharmaceutiquement acceptable de celui-ci, et une méthode permettant de traiter un trouble médical susceptible d'être traiter au moyen d'un ligand du récepteur D3 de la dopamine, ladite méthode consistant à administrer une quantité efficace d'au moins un composé représenté par la formule (I) ou d'un sel pharmaceutiquement acceptable de celui-ci.
