Abstract
A process for preparing 1,4-dihydropyridine derivatives according to the formula: * (see formula 1) *, in which R1 is phenyl, which may have one or more appropriate substituents selected from halogen, nitro, hydroxy, halomethyl, methoxy and allyloxy, or thienyl or furyl, R2 and R3 are each the same or different, esterified carboxy, and one between R4b and R5b is hydrogen, methyl or alkanoyl with 1 or 2 carbon atoms.
