An Improved Total Synthesis of PET HSV-tk Gene Expression Imaging Agent 9-[(3-[18F]Fluoro-1-hydroxy-2-propoxy)methyl]guanine ([ 18F]FHPG)
An improved total synthesis of [18F]FHPG starting from 1,3-dibenzyloxy-2-propanol and guanine has been developed. [18F]FHPG was prepared by nucleophilic substitution of the appropriate precursor with [18F]KF/ Kryptofix 2.2.2 followed by a quick deprotection reaction and purification with a simplified Silica Sep-Pak solid-phase extraction (SPE) method in 10-15% radiochemical yield, and 70 min synthesis time from end of bombardment (EOB).

Novel radiosynthesis of PET HSV-tk gene reporter probes [ 18F]FHPG and [18F]FHBG employing dual Sep-Pak SPE techniques
Positron emission tomography (PET) herpes simplex virus thymidine kinase (HSV-tk) gene reporter probes 9-[(3-[18F]fluoro-1-hydroxy-2-propoxy) methyl]guanine ([18F]FHPG) and 9-(4-[18F]fluoro-3- hydroxymethylbutyl)guanine ([18F]FHBG) were prepared by nucleophilic substitution of the appropriate tosylated precursors with [18F]KF/ Kryptofix 2.2.2 followed by a quick deprotection reaction and purification with a simplified dual Silica Sep-Pak solid-phase extraction (SPE) method in 15-30% radiochemical yield.
