Synthesis of 6-(F-18)L-fluoro-dopa using F-18 labelled acetyl hypofluorite

Conference · · J. Nucl. Med.; (United States)
OSTI ID:6793858

The synthesis of (F-18)6-fluoro-dopa via acetyl hypofluorite has recently been reported. The authors have modified this procedure by adding an acetate protecting group on the dopa ring and have treated this new starting material with either solution or gas phase F-18 acetyl hypofluorite. Using this starting material the yield has been significantly increased over the published method. The authors routinely prepare 4-5 mCi of pure (F-18)6-fluoro-dopa (3-4% radiochemical yield, at EOS) in an overall synthesis time of 2 hours. Both 2 and 6 fluoro-dopa are produced in nearly equivalent amounts by this method as determined by /sup 19/F nmr. These are easily separated by HPLC after deblocking with HI. The final isolated product is >99% in the L-isomer form and fluorinated in >97% in the 6 position.
