Claim:
A compound of formula (I), or a pharmaceutically acceptable salt or N-oxide thereof: wherein Q is a three-, four-, five- or six-membered heterocyclic ring optionally containing one or two double bonds, wherein the heterocyclic ring comprises one, two or three heteroatoms independently selected from oxygen, sulphur, nitrogen and phosphorus; R 1 is hydrogen, halogen, cyano, nitro, C 1-6 alkyl, trifluoromethyl, C 1-6 alkoxy, trifluoromethoxy, C 1-6 alkylthio, C 1-6 alkylsulphinyl or C 1-6 alkylsulphonyl; R 2 is halogen, nitro, cyano, C 1-6 alkyl, C 2-6 alkynyl, hydroxy(C 1-6 )alkyl or formyl; R 3 and R 4 are each independently hydrogen, C 1-6 alkyl, C 1-6 alkoxy, C 1-6 alkylamino(C 1-6 )alkoxy, C 1-6 alkoxy(C 1-6 )alkyl, C 1-6 alkylthio, C 1-6 alkylsulphonyl, hydroxy, hydroxy(C 1-6 )alkyl, amino(C 1-6 )alkyl, nitro(C 1-6 )alkyl, halogen, cyano, trifluoromethyl, aryl, aryl(C 1-6 )alkyl, C 3-7 heterocycloalkyl(C 1-6 )alkyl, heteroaryl, heteroaryl(C 1-6 )alkyl, oxo, thioxo, imino, C 2-6 alkylcarbonyl, carboxy, C 2-6 alkoxycarbonyl, amino, C 1-6 alkylamino, di(C 1-6 )alkylamino, bis[hydroxy(C 1-6 )alkyl]-amino, C 1-6 alkylamino(C 1-6 )alkylamino, C 3-7 cycloalkylamino, arylamino, heteroarylamino, C 2-6 alkylcarbonylamino, C 2-6 alkoxycarbonylamino, (C 2-6 )alkoxycarbonyl(C 1-6 )alkylamino, [(C 2-6 )alkoxycarbonyl][(C 1-6 )alkyl]amino, bis[(C 2-6 )alkoxycarbonyl(C 1-6 )alkyl]amino, C 2-6 alkoxycarbonylamino(C 1-6 )alkyl or aminocarbonyl; or R 3 and R 4 , when taken together with the carbon atom to which they are both attached, form a C 3-7 cycloalkyl or a C 3-7 heterocycloalkyl, said C 3-7 cycloalkyl or said C 3-7 heterocycloalkyl optionally substituted by one or more substituents independently selected from C 1-6 alkyl, hydroxy and amino; and R 5 is hydrogen or C 1-6 alkyl.
