专利号:US-10160695-B2 优先权日:2016-04-26 标 题 :Synthesis of meta-substituted [18F]-3-fluoro-4-aminopyridines by direct radiofluorination of pyridine N-oxides 发明人:BRUGAROLAS PEDRO 权利人:UNIV CHICAGO 摘要:Disclosed herein are methods for the fluorination aromatic N-heterocyclic N-oxides that comprise at least one leaving group. The N-oxides may be reduced to the fluorinated aromatic N-heterocyclic amine analogs. This novel fluorination approach may be successfully applied for synthesizing aromatic N-heterocyclic compounds labeled with 18 F.
