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;
Y is O, S, —CH═N—, —CH═CH— or —N═CH—;
A is CH2, O or S;
E is CR6R7 or NR3;
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, C2-C4-alkyl, C3-C4-cycloalkyl, C3-C4-alkenyl, fluorinated C1-C4-alkyl, fluorinated C3-C4-cycloalkyl, or R1a and R2 together are (CH2)n with n being 2 or 3, or R1a and R2a together are (CH2)n with n being 2 or 3;
R2 and R2a are independently of each other H, CH3, CH2F, CHF2 or CF3;
R3 is H or C1-C4-alkyl;
R6, R7 independently of each other are selected from H, C1-C2-alkyl and fluorinated C1-C2-alkyl;
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.
