We have completed a convenient synthesis of fluorine-18 labeled butyrophenone neuroleptics from their nitro precursors. Thus, we have developed an efficient single-column 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-step 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.
我们已经完成了从其硝基前体合成氟-18标记的丁基苯酮神经安定剂的便捷方法。因此,我们开发了一种高效的单柱高效液相色谱(HPLC)系统,使用C18键合的乙烯醇共聚物凝胶(十八烷基聚合物,ODP)柱和强碱性溶剂体系,来纯化通过一步氟-18与硝基交换反应获得的氟-18标记的丁基苯酮神经安定剂。该方法已应用于合成两种典型的丁基苯酮神经安定剂([18F]氟哌啶醇和[18F]斯皮洛酮),具有高产率和高纯度。通过优化氟-18与硝基交换反应的条件,这种合成方法将有助于合成各种氟-18标记化合物。
