ABSTRACT:
A compound of the formula ##STR1## in which R.sub.1 denotes optionally substituted lower akyl which is optionally branched at the linking carbon atom, R.sub.2 represents hydrogen or lower alkanoyl and R.sub.3 is a group of the formula --R.sub.3.sup.a -(R.sub.3.sup.b).sub.n -- (Ia), in which R.sub.3.sup.1 represents the radical of the formula --N(R.sub.4)-- or --O-- and R.sub.4 represents hydrogen or lower alkyl, R.sub.3.sup.b denotes the radical of the formula --CH.sub.2 -- or, if R.sub.3.sup.a represents --N(R.sub.4)--, denotes the radical of the formula --C(.dbd.O)-- and n represents nought or 1, and a group of the formula Ia, in which n represents 1, can be linked to the carbonyl group of the carbamoyl grouping either via the group R.sub.3.sup.a or the group R.sub.3.sup.b, or acid addition salts thereof, which can be used pharmaceutically can be used as beta-receptor blocking agents for the treatment of disorders in the cardiac rhythm and coronary heart diseases. These compounds also possess a cardio-stimulating action; some of them also display alpha-receptor-blocking properties.
