  • Preparation of pet precursor
    Patent number: 9278916
    Abstract: The invention relates to a process for preparation of radiopharmaceutical precursors, and in particular protected amino acid derivatives which are used as precursors for production of radiolabeled amino acids for use in in vivo imaging procedures such as positron emission tomography (PET). Particularly, the invention relates to a process for preparation of a precursor of the [18F]-1-amino-3-fluorocyclobutanecarboxylic acid ([18F] FACBC) PET agent and particularly to the work-up process of this precursor removing generated salts from the intermediate composition.
    Type: Grant
    Filed: November 28, 2011
    Date of Patent: March 8, 2016
    Assignee: GE Healthcare Limited
    Inventors: Tom Christian Berg, Anne Nilsen
  • Purification of precursor compound by crystallisation
    Patent number: 9061977
    Abstract: The invention relates to a process for preparation of radiopharmaceutical precursors, and in particular protected amino acid derivatives which are used as precursors for production of radiolabelled amino acids for use in vivo imaging procedures such as positron emission tomography (PET). Particularly, the invention relates to a process for preparation of a precursor useful in the preparation of the [18F]-1-amino-3-fluorocyclobutanecarboxylic acid ([18F] FACBC) PET tracer.
