Abstract
Process for obtaining 1,4-dihydropyridines having a coronary effect, of the formula: ## str3 ## in which r is hydrogen or a linear, branched or cyclic, saturated or unsaturated alkyl radical with 1 to 6 carbon atoms carbon that can be substituted by a hydroxy or alkoxy group with 1 to 3 carbon atoms, or a benzyl or phenethyl radical whose aryl moiety can be substituted by 1 to 3 alkoxy groups and/or 1 to 2 alkyl groups and/or 1 to 2 halogen atoms. R "means a linear or branched alkyl radical with 1 to 4 carbon atoms, r" means an alkyl radical having 1 to 6 carbon atoms which can be straight or branched or cyclic chain and be saturated or unsaturated and can be interrupted in the chain by 1 to 2 oxygen atoms and substituted by a hydroxy group, and r "'" means an aryl radical substituted by 1 to 2 alkyl groups optionally substituted by fluorine atoms, by 1 to 2 alkoxy groups and 1 to 2 halogen atoms.
