The present invention relates to new D3 dopamine receptor subtype selective ligands of Formula (I), wherein R1, R2 and R3 independently represent substituents selected from hydrogen, halogen, C1-6alkyl, C1-6alkoxy, cyano, hydroxy, trifluoromethyl, C1-6alkylsulfonyloxy, trifluoromethanesulfonyloxy, optionally substituted C1-6alkanoyloxy, amino, aminoalkyl, carboxy, aminocarbonyl, N-hydroxycarbamimidoyl, carbamimidoyl, hydroxycarbamoyl, thiocarbamoyl, sulfamoyl, optionally substituted phenyl or naphthyl, optionally substituted mono or bicyclic heterocyclic group, two adjacent groups of R1, R2 and R3 may combine to form an optionally substituted fused mono or bicyclic heterocyclic group, with the exception of compounds wherein a) R1= R2 = R3 = H, b) R1 = R2= H and R3 = C1-6alkoxy in the position 2 or R3 is in the position 4 of the piperazinylphenyl moiety, c) R1 = H and R2 = R3 = C1-6alkoxy; Q represents an optionally substituted C1-6alkyl, C1-6alkenyl, phenyl or heteroaryl group.
