The present invention relates to novel .alpha.1-adrenoceptor antagonists of the formula I Image I in which: R1 is acetylamino, amino, cyano, trifluoroacetylamino, halo, hydro, hydroxy, nitro, methylsulfonylamino, 2-propynyloxy, a group selected from (C1-6)alkyl, (C3-6)cycloalkyl, (C3-6)cycloalkyl(C1-4)alkyl, (C1-6)alkyloxy, (C3-6)cyclo- alkyloxy, (C3-6)cycloalkyl(C1-4)alkyloxy and (C1-4)alkylthio (which group is optionally further substituted with one to three halo atoms) or a group selected from aryl, aryl(C1-4)- alkyl, heteroaryl, heteroaryl(C1-4)alkyl, aryloxy, aryl(C1-4)alkyloxy, heteroaryloxy and heteroaryl(C1-4)alkyloxy (which aryl and heteroaryl are optionally further substituted with one to two radicals independently selected from halo and cyano); R2 is cyano, halo, hydro, hydroxy or a group selected from (C1-6)alkyl and (C1-6)alkyloxy (which group is optionally further substituted with one to three halogen atoms); R3 and R4 are both hydro or methyl or together are ethylene; and R5 is a group selected from Formulae (a), (b), (c) and (d): -2- Image Image Image Image (a) (b) (c) (d) in which: X is C(O), CH2 or CH(OH); Y is CH2 or CH(OH); Z is N or C(R9), wherein R9 is hydro, (C1-6)alkyl or hydroxy; R6 is hydro, a group selected from (C1-6)alkyl, (C3-6)- cycloalkyl, (C3-6)cycloalkyl(C1-4)alkyl (which group is optionally further substituted with one to three halo atoms) or a group selected from aryl, heteroaryl, aryl(C1-4)alkyl and heteroaryl(C1-4)alkyl (which aryl and heteroaryl are optionally further substituted with one to three radicals selected from halo, cyano, (C1-6)alkyloxy, (C1-6)alkyl and aryl); R7 is (C1-6)alkanoyl, carbamoyl, cyano, di(C1-6)alkylamino, halo, hydro, hydroxy, hydroxyiminomethyl, (C1-6)alkylsulfonyl, (C1-6)alkylthio, a group selected from (C1-6)alkyl, (C3-6)cycloalkyl, (C1-6)alkyloxy and (C1-6)alkyloxy(C1-4)alkyl (which group is optionally further substituted with one to three radicals selected from halo, hydroxy or (C1-6)alkyloxy) or a group selected from aryl, heteroaryl, aryl(C1-4)alkyl and heteroaryl(C1-4)alkyl (which aryl and heteroaryl are optionally further substituted with one to three radicals selected from halo, cyano, (C1-6)alkyloxy, (C1-6)alkyl and aryl) or R7 and R9 together are tetramethylene; and each R8 is independently hydro, hydroxy, methyl or ethyl; and the pharmaceutically acceptable salts and N-oxides thereof.
