Abstract

1525011 Process for preparing vincaminic acid basic esters LABORATORIOS FUNK SA 5 Aug 1975 [7 Aug 1974] 32708/75 Heading C2C [Also in Division A5] The process comprises a process for producing a compound of the Formula IVa or IVb in which R 1 is alkyl, R 2 is hydroxy, R 3 and R 4 are methyl or ethyl, n is an integer from 2 to 6 inclusive and a, b and c are 0, 1 or 2, and acid addition salts thereof, in which a compound of the Formula I in the form of a heavy metal salt, the metal having an atomic number between 42 and 83 both inclusive, is reacted with a compound of the Formula II or III Vincaminic acid is prepared by hydrolysis of vincamine. The sodium salt is prepared from the free acid. 2-Dimethylamino ethyl chloride is prepared by reacting its hydrochloride salt with excess base.
