E. Hedberg et B. Langstrom, SYNTHESIS OF 4-([F-18]FLUOROMETHYL)PHENYL ISOTHIOCYANATE AND ITS USE IN LABELING OLIGONUCLEOTIDES, Acta chemica Scandinavica, 51(12), 1997, pp. 1236-1240
4-([F-18] Fluoromethyl)phenyl isothiocyanate 8 was obtained from [F-18
]fluoride and 4-(4-toluenesulfonyloxymethyl)phenyl isothiocyanate 5 in
13-15% isolated, decay-corrected radiochemical yield within 40 min fr
om the end of cyclotron bombardment. The precursor 8 was used to label
the oligonucleotide 5'-GCT,AAG,CGA,TGC,CTC, CGT-3', modified in the 5
'-position with a hexylamine linker, in the 5'-position in up to 8% ra
diochemical yield.
