Abstract

A process for the preparation of 1,4-dihydropyridine derivatives of the formula: * (See formula 1) *, in which R1 is phenyl which may have one or more appropriate substituents selected from halogen, nitro, halomethyl and allyloxy or furyl, R2 and R3 are each the same or different, esterified carboxy, and one between R4d and R5d is methyl and the other is cyano or cyanomethyl, or R4d is methyl and R3 and R5d combine to form a group.
