Aminoalkyl-substituted heterocycles

A racemic or optically active compound of the formula

• Q--C.sub.n H.sub.2n --NH--R
• wherein Q is ##STR340## where R.sub.1 is hydrogen, halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, trifluoromethyl or amino,
• R.sub.2 is hydrogen, halogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or trifluoromethyl, or
• R.sub.1 and R.sub.2, together with each other, are methylenedioxy or ethylenedioxy;
• n is an integer from 2 to 6, inclusive;
• and
• R is hydrogen, benzyl or ##STR341## where R.sub.4 is hydrogen, methyl or ethyl,
• R.sub.5, R.sub.6 and R.sub.7, which may be identical to or different from each other, are each hydrogen, halogen, hydroxymethyl, trifluoromethyl, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, cyano, --CONHR.sub.3, --CONHOH, --COOR.sub.3, R.sub.8 O--, methylsulfonylmethyl or, when one or two of R.sub.5 through R.sub.7 are other than halogen or trifluoromethyl, also --NR.sub.3 R.sub.9,
• where
• R.sub.3 is hydrogen or alkyl of 1 to 4 carbon atoms,
• R.sub.8 is hydrogen, alkanoyl of 1 to 20 carbon atoms, alkyl of 1 to 4 carbon atoms or phenyl(C.sub.1-4)alkyl and
• R.sub.9 is hydrogen, lower alkanoyl, methanesulfonyl, carbamoyl, dimethylsulfamoyl, or alkoxycarbanoyl of 2 to 5 carbon atoms,
• with the proviso that R.sub.5, R.sub.6, and R.sub.7 cannot all be tert.butyl, or
• R.sub.5 and R.sub.6, together with each other are --O--CH.sub.2 --O--, --O--CH.sub.2 CH.sub.2 --O--, --CH.dbd.CH--CH.dbd.CH--, --O--CH.sub.2 --CONH--, or --O--CO-NH,
• or a non-toxic, pharmacologically acceptable acid addition salt thereof.
