  • Process for the Preparation of Ziprasidone (5-[2-[4-(1,2-Benziosothiazol-3-Y1)-1-Piperazinyl]Ethyl]-6-Chloro-1,3-Dihydro-2H-Indol-2- One
    Publication number: 20070265447
    Abstract: The present invention provides a new and useful process for preparing 5-[2-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]ethyl]-6-chloro-1,3dihydro-2H-indol-2-one (ziprasidone) and methods for its purification. The process comprises the steps of: (i) mixing 6-chloro-5-(2-chloroethyl)-1,3-dihydro-2H-indol-2-one with either a free base or salt form of 3-(1-piperazinyl)-1,2-benzoisothiazole, in the presence of an alkaline compound and a high-boiling polar organic solvent or mixture of high boiling polar organic solvents, (ii) heating the mixture and stirring for a sufficient amount of time to obtain ziprasidone formation, (iii) cooling the mixture, adding it to water and filtering off the product, (iv) adding water to the product and stirring the suspension, and (v) isolating crude ziprasidone.
