The invention provides compounds of formula (I): wherein: R2 and R3 independently represent various substituents; R1 and R4 independently represent H, F, Cl, Br, C1-2alkyl, C1alkoxy, OH, CN, or NO2; B represents a sulfur atom or a —CH2-group; t represents 3 or 4; and A represents an optionally substituted 5- or 6-membered aromatic heterocyclic ring, or an optionally substituted bicyclic heterocyclic ring system in which at least the ring bound to the group B in Formula (I) is aromatic; or a salt thereof. Preferably, A is selected from one of the groups (i), (ii) or (iii): wherein X1 and X2 are independently N or CR8, and X3 is NR8, O or S; Y1 and Y3 are independently N or CR9, and Y2 is NR9, O or S; Z1 is NR10, O or S, and Z2 and Z3 are independently N or CR10; R8, R9, and R10 are as herein defined, and R7 is H, a halogen atom, OH, cyano, nitro, C1-4alkyl, C1-4alkoxy, C1-4alkylenedioxy, C1-4alkanoyl, or C1-4alkylsulfonyl, an optionally substituted 3-, 4-, 5- or 6-membered cycloalkyl ring, or a group of the formula (a), (b), (c) or (d) as defined by the formulas (a), (b), (c) or (d). The compounds are modulators of dopamine D3 receptors and have potential in the treatment of psychotic conditions (e.g. schizophrenia) or substance abuse.
