Substituted pyridylethanolamines, methods for their preparation and their use as promoters for producing livestock

摘要

For promoting livestock production, the novel substituted pyridylethanolamines of the formula ##STR1## in which R.sup.1 represents CN, --COOR.sup.8 or --CONR.sup.9 R.sup.10,PPR.sup.2 represents optionally substituted alkyl,PPR.sup.3 represents hydrogen, alkyl or alkenyl,PPR.sup.4 represents hydrogen or optionally substituted alkyl or alkenyl, or PPR.sup.3 and R.sup.4 represent, together with the nitrogen atom to which they are bonded, an optionally substituted heterocyclic radical,PPR.sup.5 represents OH, acyloxy or alkoxy, PPR.sup.6 represents hydrogen or alkyl,PPR. sup.7 represents hydrogen, alkyl, cycloalkyl, substituted alkyl, optionally substituted aralkyl, aryl or heterocyclyl,PPR. sup.6 and R.sup.7 can, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical,P PR.sup.8 represents alkyl, andPPR.sup.9 and R. sup. 10, independently of one another, represent hydrogen, alkyl or alkenyl or, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical,P Por a physiologically tolerated salt or N-oxide thereof. Some intermediates are also new.
