We have completed a convenient synthesis of fluorine-18 labeled butyrophenone neuroleptics from their nitro precursors. Thus, we have developed an efficient single-columm HPLC system using a C18-bonded vinyl alcohol copolymer gel (octadecyl polymer, ODP) column and strongly alkaline solvent systems for purifying of the 18F-labeled butyrophenone neuroleptics obtained by a single-stp 18F-for-nitro exchange reaction. The method has been applied to the synthesis of two typical butyrophenone neuroleptics ([18F]haloperidol and [18F]spiperone) with high purity in high yield. With information concerning the optimized conditions for the 18F-for-nitro exchange reaction, the synthetic method would be useful for synthesizing various 18F-labeled compounds.
