摘要: Eszopiclone is prepared by reacting zopiclone with an enatiomerically pure di-p-toluoyl tartaric acid, recovering a solid salt, and reacting a solid salt with a base. Zopiclone is prepared by reacting 6-(5-chloropyrid-2-yl)-5-hydroxy-7-oxo-5,6-dihydropyrrolo[3,4-b]-pyrazine with 1-chlorocarbonyl-4-methylpiperazine hydrochloride.
