Abstract

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, ...
