Abstract

4-Heterocyclophenyl-substituted dihydropyridines ##STR1## are prepared either by reacting suitable aldehydes with amino esters and .beta.-keto esters, or preparing the heterocyclic substituents of the 4-phenyl by cyclization of corresponding amidines or hydrazides, or esterifying dihydropyridinecarboxylic acids, which are already substituted by heterocyclic radicals, with corresponding alcohols. The 4-heterocyclophenyl-substituted dihydropyridines can be employed in medicaments, in particular for treatment of diseases of the central nervous system.
