AMINOMETHYL SUBSTITUTED BICYCLIC AROMATIC COMPOUNDS SUITABLE FOR TREATING DISORDERS THAT RESPOND TO MODULATION OF THE DOPAMINE D3 RECEPTOR.

摘要

The present invention relates to an aminomethyl substituted bicyclic aromatic compound of the formula (I) wherein Ar is a cyclic radical selected from the group consisting of phenyl, a 5- or 6-membered C-bound heteroaromatic radical comprising as ring member 1, 2 or 3 heteroatoms which are, independently of each other, selected from O, S and N, and a phenyl ring fused to a saturated or unsaturated 5- or 6-membered carbocyclic or heterocyclic ring, where the heterocyclic ring comprises as ring members 1, 2 or 3 heteroatoms selected from N, O and S and/or 1, 2 or 3 heteroatom-containing groups each independently selected from NR8, where R8 is H, C1-C4-alkyl, fluorinated C1-C4-alkyl, C1-C4-alkylcarbonyl or fluorinated C1-C4-alkylcarbonyl, and where the cyclic radical Ar may carry 1, 2 or 3 substituents Ra, wherein the variable Ra has the meanings given in the claims and in the description; X is a covalent bond or N-R2, CHR2, CHR2CH2, N or C-R2; Y is N-R2a, CHR2a, CHR2aCH2 or CHR2aCH2CH2; is a single bond or a double bond; E is CH2 or NR3; R1 is H, C1-C4-alkyl, C3-C4-cycloalkyl, C3-C4-cycloalkylmethyl, C3-C4-alkenyl, fluorinated C1 i-C4-alkyl, fluorinated C3-C4-cycloalkyl, fluorinated C3-C4-cycloalkylmethyl, fluorinated C3 i-C4-alkenyl, formyl or C1-C3-alkylcarbonyl; R1a is H, C1-C4-alkyl, C3-C4-cycloalkyl, C3-C4-alkenyl, fluorinated C1-C4-alkyl, fluorinated C3 i-C4-cycloalkyl, fluorinated C3-C4-alkenyl, R2 and R2a each independently are H, CH3, CH2F, CHF2 or CF3 or R1a and R2 or R1a and R2a together are (CH2)n with n being 1, 2 or 3; R3 is H or C1-C4-alkyl; R4 and R5 independently of each other are H, C1-C4-alkyl, fluorinated C1-C4-alkyl or C1-C4 i-alkoxy or may form, together with N, a 4-, 5- or 6-membered saturated or unsaturated ring; R6 and R7 independently of each other are H or halogen; 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 there of for preparing a pharmaceutical composition for the treatment of a medical disorder susceptible to treatment with a dopamine D3 receptor ligand.
