Abstract
New Pyridine derivatives of the formula ##STR1## wherein group Y or one of the groups Z is N and the others of these groups being in each case CH; n is 1, 2 or 3; R is ##STR2## R.sup.1 and R.sup.2 are in each case phenyl or 2- or 3-thienyl radicals which are unsubstituted or mono- or di-substituted by an alkyl and/or alkoxy having 1-4 C atoms, F, Cl, Br, OH and/or CF.sub.3 ; and R.sup.3 and R.sup.4 are in each case H, alkyl or alkoxy having 1-4 C atoms, F, Cl, Br, OH or CF.sub.3 ; and their salts with the proviso that, Y is CH when R is ##STR3##
