    • The present invention relates to an improved preparing method of ( S )-omeprazole from omeprazole racemate. In an exemplary embodiment, the preparing method according to the present invention comprises the steps of: a) reacting omeprazole racemate with optically active diethyl-D-tartrate and a titanium compound in an alcohol solvent to prepare an omeprazole racemic complex; b) reacting the omeprazole racemic complex with 1.5-3.0 molar equivalents of ( S )-(+)-mandelic acid as optical resolution agent to prepare an optically active ( S )-omeprazole complex; and c) dissociating the optically active ( S) -omeprazole complex with a basic solution to prepare an ( S )-omeprazole free base or reacting the ( S )- omeprazole free base with a metal salt to transfer to a metal salt or a metal salt hydrate of ( S )- omeprazole. With optical purity of 99.0 %ee or better, the ( S )-omeprazole, the metal salt thereof or the hydrate thereof prepared in accordance with the present invention is useful as a medicinal material.
