Abstract
Abstract A method for the treatment and/or prophylaxis of cerebrovascular disorders and/or disorders associated with cerebral senility in mammals, such as humans, which comprises administering to the mammal in need of such treatment and/or prophylaxis an effective and/or prophylactic amount of a compound of formula (I): wherein: n is 1 or 2; R₁ is chloro, bromo, C 1-6 alkylcarbonyl or cyano; one of R₃ and R₄ is hydrogen or C 1-4 alkyl and the other is C 1-4 alkyl or R₃ and R₄ together are C 2-5 polymethylene; and either R₅ is hydroxy, C 1-3 alkoxy or C 1-8 acyloxy; and R₂ is hydrogen and the cyclic amide moiety and R₅ are trans ; or R₅ and R₂ together form a bond, novel compounds within formula (I), processes for their preparation.
