PROCEDURE FOR OBTAINING 1,4-DIHYDROPYRIDINES AND ITS PHYSIOLOGICALLY COMPATIBLE ACID ADDITION SALTS, OF FORMULA (I), IN WHICH Y IS - (CH2) 2- O - (CH2) 3-; R IS ARYL OR HETEROARYL; R ELEVATED 1 AND R ELEVATED 2 ARE C1-4 ALKYL OR 2-METHOXYETHYL; AND R HIGH 3 AND R HIGH 4 CAN BE SEVERAL RADICALS. IT CONSISTS OF THE REATION OF A COMPOUND OF FORMULA (II) WITH A COMPOUND OF FORMULA (III), IN WHICH ALL THE SYMBOLS HAVE THE SAME MEANING AS IN FORMULA (I). THE REACTION IS CARRIED OUT IN AN INERT ORGANIC SOLVENT, SUCH AS A C1-4 ALCANOL, AT A TEMPERATURE INCLUDED BETWEEN 60GC AND 130GC. *FORMULA*. T |
