The fluorine-18 labeled nortropane derivative 2β-carbomethoxy-3β- (4-chlorophenyl)-8-(2-fluoroethyl)-nortropane (FECNT) is a dopamine transporter (DAT) ligand. Currently, it is considered as reference for positron emission tomography imaging. Herein, the synthesis of novel precursors (N-tosyloxy-, chloro-, and bromo- analogues) for one-step radiosynthesis of [ 18F]FECNT is reported. Using the N-mesyloxy- precursor in a one-step radiosynthesis, the crude [18F]FECNT was obtained with the radiolabeling yield of 45 ± 10%, confirming the practical efficiency of this approach in the design of novel precursors for labeling.

A novel series of tropane derivatives containing a fluorinated tertiary amino or amide at the 2β position was synthesized, labeled with the positron-emitter fluorine-18 (t1/2 = 109.8 min), and tested as potential in vivo dopamine transporter (D
