3-Substituted 2-amino-3,4-dihydropyridine-3-carboxylic acid esters are produced by reacting 2-amino-1,4-dihydropyridine-3-carboxylic acid esters with an alkylating agent in the presence of an inert organic solvent at a temperature of from 20.degree. C to 200.degree. C. The compounds, of which 2-amino-3,6-dimethyl-4-phenyl-3,4-dihydropyridine-3,5-dicarboxylic acid diethyl ester is a typical embodiment, possess antihypertensive and coronary dilating properties.
3-取代基的2-氨基-3,4-二氢吡啶-3-羧酸酯可以通过在惰性有机溶剂中,在20℃至200℃的温度下,将2-氨基-1,4-二氢吡啶-3-羧酸酯与烷基化试剂反应而制备得到。这些化合物具有降压和扩张冠状动脉的特性,其中2-氨基-3,6-二甲基-4-苯基-3,4-二氢吡啶-3,5-二羧酸二乙酯是其中的一个典型实例。
