摘要： [C-14]Quincetone was prepared from (BaCO3)-C-14 with a radiochemical yield of 21.3%. (BaCO3)-C-14, as starting material, was acidified to release (CO2)-C-14, which reacted with PhMgBr to [C-14]benzoic acid. [C-14]Benzoic acid was reduced with LiAlH4 to [C-14]benzyl alcohol, and oxidized with CrO3 to [C-14]benzaldehyde. In the last reaction, [C-14]benzaldehyde was condensed with 3-methyl-2-acetyl-quinoxaline-1,4-dioxide to [C-14]quincetone. The specific radioactivity of the labeled product was 7.76 mCi/mmol and its radiochemical purity was >97%.
