Abstract
Abstract We have completed rapid syntheses of [18F]butyrophenone neuroleptics ([18F]haloperidol and [18F]spiperone) from their nitro precursors in high radiochemical yields (up to 21%) by combining a one-step nitro-fluoro exchange reaction and a novel high performance liquid chromatography (HPLC) separation method. The synthesis time was ca. 95 min and both the radiochemical and chemical purities of the labeled products were over 99%.
