  • Patent number: 4335256
    Abstract: A two-step process for manufacturing d,l-.beta.-benzoylamino-isobutyric acid is disclosed, wherein in the first step benzamide is reacted with methacrylonitrile in the presence of an alkaline catalyst in an anhydrous solvent medium at atmospheric pressure, thus obtaining d,l-.beta.-benzoylamino-isobutyronitrile, which, in the second process step, without necessarily being previously crystallized is directly hydrolyzed to d,l-.beta.-benzoylamino-isobutyric acid.
    Type: Grant
    Filed: November 16, 1978
    Date of Patent: June 15, 1982
    Assignee: Sigma-Tau Industrie Farmaceutiche Riunite S.p.A.
    Inventors: Paolo de Witt, Enrico Diamanti
  • Patent number: 4254053
    Abstract: A process for manufacturing the D camphorate of L carnitinamide and the D camphorate of D carnitinamide is disclosed, wherein D,L carnitinamide hydrochloride is converted to D,L carnitinamide free base which directly reacts with D camphoric acid either as an aqueous suspension or in solid form, thus obtaining a solution of D camphorate of D,L carnitinamide. The resolution of the optical isomers is achieved by drying this solution and taking up the residue with isopropanol, whereupon the D camphorate of L carnitinamdide crystallizes out of the isopropanol solution and the D camphorate of D carnitinamide remains in solution.
