Process for preparation of chiral amlodipine salts

   
   

A process for the preparation of pharmaceutically acceptable salts of chiral Amlodipine namely S(-) Amlodipine and R(+) Amlodipine from without isolation of a free base from with optical purity rank between 96-99% is described in the present invention. The process comprises resolving RS amlodipine base using of L(+) or D(-) tartaric acid to obtain salt of corresponding to the acid used in ee rang from 96-99%.

Un proceso para la preparación de sales farmacéutico aceptables de Amlodipine chiral es decir S(-) Amlodipine y R(+) Amlodipine sin del aislamiento de una base libre con de la fila óptica de la pureza entre 96-99% se describe en la actual invención. El proceso abarca usar bajo de resolución del amlodipine de RS de L(+) o D(-) el ácido tartárico para obtener la sal de corresponder al ácido utilizó en ee sonó a partir de la 96-99%.
