The invention provides compounds of formula (I)wherein A and B represent the groups -(CH2)m- and -(CH2)n-respectively; R1 represents hydrogen or C1-6alkyl; R2 represents hydrogen, halogen, hydroxy, cyano, nitro, hydroxyC1-6alkyl, trifluoromethyl, trifluoromethoxy, C1-6alkyl, C1-6alkoxy, C1-6alkoxyC1-6alkyl, C3-7cycloalkylC1-6alkoxy, -(CH2)pC3-6cycloalkyl, -(CH2)pC3-6cycloalkyloxy, -COC1-6alkyl, -SO2C1-6alkyl, -SOC1-6alkyl, -S-C1-6alkyl, C1-6alkylsulfonyloxy, C1-6alkylsulfonylC1-6alkyl, -CO2C1-6alkyl, -CO2NR7R8, -SO2NR7R8, C1-6alkylsulfonamido, C1-6alkylsulfonamidoC1-6alkyl, -(CH2)pNR7R8, C1-6alkylamidoC1-6alkyl, -(CH2)pNR7COR8, arylsulfonyl, arylsulfonyloxy, arylsulfonylC1-6alkyl, arylsulfonamido, arylcarboxamido, arylsulfonamidoC1-6alkyl, arylcarboxamidoC1-6alkyl, aroyl, aroylC1-6alkyl, arylC1-6alkanoyl, -SO2NR7R8, optionally substituted aryl, optionally substituted heteroaryl or optionally substituted heterocyclyl, or a group CONR7R8 or SO2NR7R8 wherein R7 and R8 together may be fused to form a 5- 7-membered aromatic or non-aromatic heterocyclic ring optionally interrupted by an O or S atom; R3 represents hydrogen or C1-6alkyl; Ar represents optionally substituted phenyl or optionally substituted monocyclic heteroaryl group; R4 represents optionally substituted aryl or optionally substituted heteroaryl; R7 and R8 each independently represent hydrogen, C1-6alkyl or together form a 5- to 7-membered heterocyclic ring; Z represents a bond, an oxygen atom or C1-6alkyl:Y represents hydrogen or C1-6alkyl; m and n independently represent an integer selected from 1 and 2; p independently represents an integer selected from 0, 1, 2 and 3; q represents an integer from 1 to 3; r represents an integer from 1 to 4; or a pharmaceutically acceptable salt or solvate thereof. The compounds are useful in therapy, in particular as antipsychotic agents. |
