摘要

Compounds of formula (I), wherein: R1 represents a substituant selected from: a hydrogen or halogen atom; a hydroxy, cyano, nitro, trifluoromethyl, trifluoromethoxy, trifluoromethanesulfonyloxy, C¿1-4?alkyl, C1-4alkoxy, arylC1-4alkoxy, C1-4alkylthio, C1-4alkoxyC1-4alkyl, C3-6cycloalkylC1-4alkoxy, C1-4alkanoyl, C1-4alkoxycarbonyl, C1-4alkylsulfonyl, C1-4alkylsulfonyloxy, C1-4alkylsulfonylC1-4alkyl, arylsulfonyl, arylsulfonyloxy, arysulfonylC1-4alkyl, C1-4alkylsulfonamido, C1-4alkylamido, C1-4alkylsulfonamidoC1-4alkyl, C1-4alkylamidoC1-4alkyl, arylsulfonamido, arylcarboxamido, arylsulfonamidoC1-4alkyl, arylcarboxamidoC1-4alkyl, aroyl, aroylC1-4alkyl, or arylC1-4alkanoyl group; a group R?3¿OCO(CH¿2?)p, R?3CON(R4)(CH¿2)p, R3R4NCO(CH¿2?)p or R?3R4NSO¿2(CH2)p where each of R?3 and R4¿ independently represents a hydrogen atom or a C¿1-4?alkyl group or R?3R4¿ forms part of a C¿3-6?azacycloalkane or C3-6(2-oxo)azacycloalkane ring and p represents zero or an integer from 1 to 4; or a group Ar?2¿-Z, wherein Ar2 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¿2; R?2 represents a hydrogen atom or a C¿1-4?alkyl group; q is 1 or 2; Ar and Ar?1¿ each independently represent an optionally substituted phenyl ring or an optionally substituted 5- or 6- membered aromatic heterocyclic ring; and Y represents a bond, -NHCO-, -CONH-, -CH¿2?-, or -(CH2)mY?1(CH¿2)n-, wherein Y1 represents O, S, SO¿2?, or CO and m and n each represent zero or 1 such that the sum of m+n is zero or 1; and salts thereof, have activity at dopamine receptors and are useful in the treatment of psychoses such as schizophrenia.
