The invention relates to compounds of the formula (I)
wherein
n
is 0, 1 or 2;
G
is CH2 or CHR3;
R1
is H, C1-C6-alkyl, C1-C6-alkyl substituted by C3-C6-cycloalkyl, C1-C6-hydroxyalkyl, fluorinated C1-C6-alkyl, C3-C6-cycloalkyl, fluorinated C3-C6-cycloalkyl, C3-C6-alkenyl, fluorinated C3-C6-alkenyl, formyl, acetyl or propionyl;
R 2 R3 and R4
are, independently of each other, H, methyl, fluoromethyl, difluoromethyl, or trifluoromethyl;
A
is phenylene, pyridylene, pyrimidylene, pyrazinylene, pyridazinylene or thiophenylene, which can be substituted by one ore more substituents selected from halogen, methyl, methoxy and CF3;
E
is NR5 or CH2, wherein R5 is H or C1-C3-alkyl;
Ar
is a cyclic radical selected from the group consisting of phenyl, a 5- or 6-membered heteroaromatic radical comprising as ring members 1, 2 or 3 heteroatoms selected from N, O and S 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;
and 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.
