Abstract
Un proceso, que comprende hacer reaccionar una mezcla de R- y/o S-zoplicona y/o una sal de los mismos con ácido L-tartárico en un solvente para formar una solucion que contiene iones zopiclona e iones ácido L-tartárico, y a un proceso para incrementar la pureza enantiomérica de S-zoplicona, que comprende: (a) hacer precipitar selectivamente a partir de una solucion, que contiene zoplicona y ácido tartárico como solutos y acetonitrilo como un solvente, un solvato L-tartrato de S- zoplicona acetonitrilo; y (b) tratar dicho solvato L-tartrato de S-zoplicona acetonitrilo con una base de manera de formar S-zoplicona enriquecida, y al uso de ácido L-tartárico en la produccion de S-zoplicona enriquecida y/o de su compuesto L- tartrato. Reivindicacion 1: Un compuesto, caracterizado porque es L-tartrato de S-zopiclona.
