Abstract
A process for the preparation of (S)-omeprazole from racemic omeprazole via the formation of an inclusion complex with (S)-1,1,2-triphenyl-1,2-ethanediol. (S)-Omeprazole is recovered in a substantially optically pure form either in neutral form or as a pharmaceutically acceptable salt or as its solvates including hydrates. The (S)-omeprazole 2[(S)-1,1,2-triphenyl-1,2-ethanediol] inclusion complex is new. This resolution process proceeds with high yields and high optical purity.
