  • Publication number: 20130022525
    Abstract: A method of drying a radioisotope solution having radioisotopes includes passing the radioisotope solution through a solid phase extraction column containing an anion exchange group, thereby trapping the radioisotopes in the column. The method also includes passing an eluent through the column, thereby removing the radioisotopes from the column. The eluent includes a cation trapping agent/salt complex, less than 4% water, and the remainder is a solvent. A method of producing the eluent includes reacting a cation trapping agent with a salt in the presence of less than 4% water and a solvent to form solubilized cation trapping agent/salt complex, wherein one of the cation trapping agent and the salt is present in en excess of a stoichiometric amount and ending the reaction when a predetermined amount of solubilized cation trapping agent/salt complex has been formed.

  • Publication number: 20070077198
    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.

  • Publication number: 20050137421
    Abstract: The invention relates to a method for preparing F-Dopa and 18F-Dopa and intermediates that are useful in the method. The invention is a method that synthesizes F-Dopa and 18F-Dopa in good yield with high enantiopurity without the need for further transformations. The method includes the step of reacting a benzaldehyde derivative with a phosphonic acid derivative to produces an olefin intermediate that can be asymmetrically hydrogenated to produce the desired enantiomer.

  • Publication number: 20050131224
    Abstract: The invention is a novel method and precursor for preparing radiolabeled nucleosides. In particular, the invention is useful for preparing 3?-[18F]fluorothymidine. The method uses an enol group that is attached to the 2-position on the pyrimidine ring. The enol group attenuates thymidines activity so that the thymidine is easily radiolabeled in short number of steps with good yield.
