  • Patent number: 9308174
    Abstract: New formulations of bendamustine hydrochloride having HPLC purity higher than 99% obtained through the lyophilization of aqueous solutions without organic solvents, are described.
    Type: Grant
    Filed: June 17, 2014
    Date of Patent: April 12, 2016
    Assignee: CHEMI S.P.A.
    Inventors: Stefano Turchetta, Maurizio Zenoni, Paolo Brandi
  • Patent number: 9266863
    Abstract: Described herein is a process for the synthesis of azacitidine or decitabine, comprising the silylation of azacytosine in the presence of N,O-bis-trimethylsilyl-trifluoroacetamide. Such reaction is performed in an organic solvent, preferably aprotic, even more preferably selected from among dichloromethane, dichloroethane and/or acetonitrile. According to a further aspect of the process, 2 to 3 moles of N,O-bis-trimethylsilyl-trifluoroacetamide are used per mole of azacytosine, preferably from 2.2 to 2.5.
    Type: Grant

  • Patent number: 8981090
    Abstract: The present invention relates to a novel process for the preparation of pemetrexed diethyl ester 2 by purifying the mixture obtainable by reacting compounds 1 and 1a in the presence of a chemical agent capable of promoting the formation of a peptide bond in an aprotic organic solvent characterized in that the mixture is subjected to the following steps: a) washing with a basic aqueous solution; b) concentration of the organic phase; c) addition of a polar organic solvent and/or a mixture of polar organic solvents; d) precipitation of the pemetrexed diethyl ester 2.
