O-(2-[18F]fluoroethyl)-L-tyrosine was synthesized via “one-step” method of nuclephilic radiofluorination with a precursor N-BOC-(O-2-tosyloxyethyl)-L-tyrosine methyl ester which is easy to obtain. Separation was per- formed on Sep-pak cartridge with solid phase extraction
instead of HPLC (high pressure liquid chromatography). The operation process was simple and the total synthesis time was less than 50 min. The radiochemical yield was about 40% (without decay-correction)
