Automated synthetic technology of 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) was described. Automated synthesis of F-FDG was performed by “one-pot” and “two-step reaction” procedures in TRACERlab 18 FXF-N system. 18F-FDG injection was obtained via “two-step reaction” including nucleophilic fluorination of the precursor 1

6-tetra-O-acetyl-2-O-trifluoromethanesulfony-β-D-mannopyranose with F-fluoride and hydrolysis 18 with NaOH in the same reaction vessel
and subsequently purificated with Sep-Pak cartridges. The uncorrected radiochemical yield of 18F-FDG was about 60% and radiochemical purity was more than 99% within the total synthesis time about 24 min. Improved synthesis method of F-FDG injection is simple to operate and can become a 18 practical method of preparation.
