A process for the preparation of chiral 4-hydroxy-2-oxo-1-pyrrolidine acetamide includes adding sodium cyanide together with citric acid to a solution of chiral epichlorohydrin to obtain chiral 3-chloro-2-hydroxypropionitrile by ring opening reaction of the chiral epichlorohydrin, reacting the obtained product with an alcohol containing hydrochloride gas to obtain chiral 4-chloro-3-hydroxybutyric acid ester, and reacting the obtained product in a presence of a base with glycinamide or with glycine ester accompanied by ammonolysis with ammonia to produce the targeted chiral 4-hydroxy-2-oxo-1-pyrrolidine acetamide.
