More Information
Summary:A novel form of Melperone is obtained in solid crystalline form as the base in high yield and high purity from a crude reaction mixture. Crystalline Melperone base may be used directly in various pharmaceutical formulations or it may be converted into very pure pharmaceutically acceptable salts such as Melperone hydrochloride. The process for preparing Melperone or salts thereof comprises converting a Melperone precursor into a Melperone intermediate ketal and converting the ketal intermediate into Melperone base or a salt thereof.
