摘要

Substituted pyridylethanolamines of the formula I …… in which… R<1> represents CN, -COOR<8> or -CONR<9>R<1><0>,… R<2> represents optionally substituted alkyl,… R<3> represents hydrogen, alkyl or alkenyl,… R<4> represents hydrogen, optionally substituted alkyl or alkenyl,… R<3> and R<4>, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical,… R<5> represents OH, acyloxy or alkoxy,… R<6> represents hydrogen or alkyl,… R<7> represents hydrogen, alkyl, cycloalkyl, substituted alkyl, optionally substituted aralkyl, aryl or heterocyclyl,… R<6> and R<7>, together with the nitrogen atom to which they are bonded, can represent an optionally substituted heterocyclic radical,… R<8> represents alkyl,… R<9> and R<1><0> 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,… and intermediates for carrying out these processes.
