  • Publication number: 20050119351
    Abstract: An improved process for the preparation of sertraline hydrochloride polymorphic form II is described, which process comprises seeding a solution of sertraline free amine in a ketone with some crystals of polymorphic form II and addition of hydrogen chloride, and wherein the solution is heated before addition of the hydrogen chloride. According to the present process, the metastable form II may be obtained in a reliable way with good yield and high purity with respect to other polymorphic forms as well as preparative residues such as educts or solvents.
