In an effort to make HSV-tk gene reporter probes 8-FPCV and 8-FGCV labeled with fluorine-18, via the nucleophilic substitution reaction of PCV and GCV quaternized methylamine salt precursors with KF/Kryptofix 2.2.2, a new and unusual reaction through methyl triflate was discovered. Subsequently, new compounds 8-MeOPCV and 8-MeOGCV were synthesized from PCV and GCV in six steps with 12% and 20% overall chemical yield, respectively, and a novel potential approach to label PCV and GCV with carbon-11 has been proposed.
