N ‐4‐(4‐chlorophenyl)butyl‐ N , N ‐diethyl‐7‐[ 18 F]fluoroheptylammonium ([ 18 F]‐fluoroclofilium) has been prepared as a potential cardiac imaging agent. For the synthesis of this radiolabelled ammonium salt, its tosyloxylated analogue was prepared as a precursor, and the non‐radioactive fluorine analogue was synthesized as a reference compound. Radiofluorination was achieved by the treatment of N ‐4‐(4‐chlorophenyl)butyl‐ N , N ‐diethyl‐7‐( p ‐toluenesulfonyloxy)heptylammonium p ‐toluenesulfonate with 18 F − in the presence of Kryptofix‐2.2.2 in acetonitrile.
