  • Method for preparing radiolabeled thymidine having low chromophoric byproducts
    Patent number: 7419653
    Abstract: The invention is a method and related precursor for preparing 18F-FLT. The precursor has a butoxycarbonyl protecting group at the 5?-position that results in low amounts of chromophoric byproducts being formed during deprotection. The method for preparing 18F-FLT is efficient and makes the final purification step less complicated.
    Type: Grant
    Filed: November 22, 2006
    Date of Patent: September 2, 2008
    Assignee: Siemens Medical Solutions USA, Inc.
    Inventors: Joseph C. Walsh, Henry C. Padgett, Tanea Ysaguirre
