The present invention relates to a method for preparing a 2-fluoropurine marked with the radioisotope
18
F comprising a fluorination step for a 2-nitropurine derivative. The present invention comprises a 2-fluoropurine derivative marked with the radioisotope
18
F which can be obtained by or during a method according to the invention and its various uses.
An efficient method to incorporate the fluorine-18 radionuclide in 2-nitropurine-based nucleosides was developed. The nucleophilic radiofluorination of the labeling precursor with [(18)F]KF under aminopolyether-mediated conditions (Kryptofix 2.2.2/K2CO3) followed by deprotection was straightforward and, after formulation, gave 2-[(18)F]fluoroadenosine, ready for injection with a radiochemical yield
