In this study, we have attempted to simplify the automated radiosynthesis of two [18F]fluoroethylated tracers, [18F]FEDAC and [18F]FET, using a desmethyl labeling precursor and [18F]fluoroethyl tosylate, based on the above-mentioned method. The radiochemical yields of [18F]FEDAC and [18F]FET were 26 ± 3.7% (n = 5) and 14 ± 2.2% (n = 4), respectively, based on total [18F]F– at the end of irradiation.}, title = {Radiosynthesis of 18F-fluoroethylated tracers via a simplified one-pot 18F-fluoroethylation method using [18F]fluoroethyl tosylate}, volume = {169}, year = {2021} }
