  • Publication number: 20230331727
    Abstract: Method for the production of formula (I) lumateperone or its acid addition salts so that the enantiomer compound with stereochemistry 6bR,10aS is separated form the cis racemate using resolution and the formula (II) stereoisomer is alkylated with 4-halo-4?-fluoro butyrophenone (X = I, Br, Cl) to produce the formula (I) lumateperone, or optionally its acid addition salt. The object of the invention also relates to the amorphous form of the morphologically uniform p-toluenesulfonic acid salt of lumateperone and to the naphthalene-2-sulfonic acid salt of lumateperone, to the 1:2 stoichiometry salt of lumateperone formed with naphthalene-2-sulfonic acid.

  • Patent number: 8877799
    Abstract: The present invention relates to the use of novel vildagliptin complexes for the manufacture of high purity vildagliptin of Formula I and/or pharmaceutical acceptable salts thereof. Further objects of the present invention are pharmaceutically acceptable complexes of vildagliptin and/or amorphous and crystalline forms, anhydrous forms, amorphous and crystalline hydrates, amorphous and crystalline solvates of the complexes and a process for the preparation thereof. Another object of the present invention is the high purity vildagliptin and pharmaceutically acceptable salts thereof prepared form the vildagliptin complexes of the present invention, a process for the preparation thereof and pharmaceutical compositions containing vildagliptin base, pharmaceutically acceptable salts and/or complexes and use thereof for the treatment of type 2 diabetes (NIDDM). The present invention provides pharmaceutically advantageous high purity vildagliptin complexes.
