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.
