Cyclic diamine derivatives

Abstract

Abstract A compound having the general formula or an acid addition salt thereof ##STR1## in which formula R 1 is selected from the group consisting of (A) an at least mononuclear heterocyclic group having 4 to 10 carbon atoms in the ring system bound to the group ##STR2## through a carbon atom and containing at least one oxygen, nitrogen or sulphur atom, (B) substitution products of (A) containing at least one substituent selected from the group consisting of halogen, trifluoromethyl, hydroxy, alkoxy of 1 to 3 carbon atoms, unsubstituted amino, amino substituted by up to two alkyl groups each having 1 to 3 carbon atoms and alkyl groups having 1 to 6 carbon atoms, X is oxygen, sulphur or an NH-group, Y is an alkylene group having 1 to 3 carbon atoms in the chain, or an alkylene group having 1 to 3 carbon atoms in the chain substituted by (a) up to 3 alkyl groups each having up to 3 carbon atoms and a total of not more than 8 carbon atoms, or (b) substituted by one or two phenyl groups, R 2 is selected from the group consisting of (c) an at least mononuclear carbocyclic or heterocyclic group having 4 to 10 carbon atoms in the ring system, containing but one heteroatom in a ring, (D) substitution products of (C) containing at least one substituent selected from the group consisting of nitro, halogen, trifluoromethyl, alkyl having 1 to 6 carbon atoms, hydroxy, alkoxy having 1 to 3 carbon atoms, unsubstituted amino groups and amino groups substituted by up to two alkyl groups each having 1 to 3 carbon atoms, R 3 is hydrogen or up to two substituents selected from alkyl groups having up to 2 carbon atoms and phenyl groups. n is 2 or 3; a process for its preparation and a pharmaceutical composition containing said compound (I).
