Compounds of formula (I), wherein R.sup.1 represents a substituent selected from: a hydrogen or halogen atom; a hydroxy, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethanesulfonyloxy, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, arylC.sub.1-4 alkoxy, C.sub.1-4 alkylthio, C.sub.1-4 alkoxyC.sub.1-4 alkyl, C.sub.3-6 cycloalkylC.sub.1-4 alkoxy, C.sub.1-4 alkanoyl, C.sub.1-4 alkoxycarbonyl, C.sub.1-4 alkylsulphonyl, C.sub.1-4 alkylsulphonyloxy, C.sub.1-4 alkylsulphonylC.sub.1-4 alkyl, arylsulphonyl, arylsulphonyloxy, arylsulphonylC.sub.1-4 alkyl, C.sub.1-4 alkylsulphonamido, C.sub.1-4 alkylamido, C.sub.1-4 alkylsulphonamidoC.sub.1-4 alkyl, C.sub.1-4 alkylamidoC.sub.1-4 alkyl, arylsulphonamido, arylcarboxamido, arylsulphonamidoC.sub.1-4 alkyl, arylcarboxamidoC.sub.1-4 alkyl, aroyl, aroylC.sub.1-4 alkyl, or arylC.sub.1-4 alkanoyl group; a group R.sup.3 OCO(CH.sub.2).sub.p, R.sup.3 CON(R.sup.4)(CH2)p, R.sup.3 R.sup.4 NCO(CH.sub.2).sub.p or R.sup.3 R.sup.4 NSO.sub.2 (CH.sub.2).sub.p where each of R.sup.3 and R.sup.4 independently represents a hydrogen atom or a C.sub.1-4 alkyl group or R.sup.3 R.sup.4 forms part of a C.sub.3-6 azacyloalkane or C.sub.3-6 (2-oxo)azacycloalkane ring and p represents zero or an integer from 1 to 4; or a group Ar.sup.1 Z, wherein Ar.sup.1 represents an optionally substituted phenyl ring or an optionally substituted 5- or 6-membered aromatic heterocyclic ring and Z represents a bond, O, S, or CH.sub.2 ; represents a hydrogen atom or a C.sub.1-4 alkyl group; q is 1 or 2; Ar represents an optionally substituted phenyl ring or an optionally substituted 5- or 6-membered aromatic ring; or an optionally substituted bicyclic aromatic or heteroaromatic ring system; and salts thereof. Compounds of formula (I) and their salts have affinity for dopamine receptors, in particular the D.sub.3 receptor, and thus potential in the treatment of conditions wherein modulation of the D.sub.3 receptor is beneficial, e.g. as antipsychotic agents.
