PROCESS FOR PRODUCTION OF COMPOUND LABELED WITH RADIOACTIVE FLUORINE

A process for production of 18 F-FDG is provided, which can produce 18 F-FDG in a high and stable yield of synthesis. A process for production of a compound labeled with radioactive fluorine comprises the steps of: preparing a reaction solution by adding, under a hermetic condition, TATM and an inert organic solvent to a mixture containing [ 18 F]fluoride ions, a phase transfer catalyst and potassium ions; giving a reaction condition to the reaction solution under a hermetic condition to obtain 18 F-TAFDG; and subjecting the obtained 18 F-TAFDG to a deprotection process and optionally to a purification process to obtain 18 F-FDG.
