und ihrer nicht-toxischen Säureadditionssalze. In der vorstehenden Formel steht η für 0 oder 1, R für einen niederen Alkylenrest mit gerader oder verzweigter Kette; R1 und R^ können, gesondert betrachtet, gleich oder verschieden sein und jeweils ein Wasserstoffatom oder einen niederen Alkylrest oder einen Phenylrest oder einen substituierten Phenylrest (mit einer oder mehreren Hydroxylgruppen, niederen Alkylresten, Trifluormethyl- oder Carboxylgruppen als Substituenten) oder einen niederen Dialkylrest, niederen Aminoalkylrest darstellen, wobei jedoch R1 und R2 nicht beide ein Wasserstoffatom sein können, oder R1 und Rg können mit dem Stickstoff, an den sie gebunden «sind, an einem Heterocyclus beteiligt sein*Alsand their non-toxic acid addition salts. In the above formula, η is 0 or 1, R is a lower alkylene radical with a straight or branched chain; Considered separately, R 1 and R ^ can be identical or different and each represent a hydrogen atom or a lower alkyl radical or a phenyl radical or a substituted phenyl radical (with one or more hydroxyl groups, lower alkyl radicals, trifluoromethyl or carboxyl groups as substituents) or a lower dialkyl radical , represent lower aminoalkyl radical, where, however, R 1 and R 2 cannot both be a hydrogen atom, or R 1 and R g can be involved in a heterocycle with the nitrogen to which they are attached * Als
