A method of preparing fluorine-18 labeled radiopharmaceuticals (
18
F-radiopharmaceuticals) is disclosed. More particularly, the present invention relates to a method of preparing an
18
F-radiopharmaceutical by reacting a salt containing fluorine-18 (
18
F) with an alkyl halide or an alkyl sulfonate in the presence of water and ethanol to obtain a high yield of the
18
F-radiopharmaceutical. The synthetic method eliminates the use of toxic and/or environmentally-unfriendly organic solvents.
本发明公开了一种制备
氟-18标记的放射性药物(18F-放射性药物)的方法。更具体地说,本发明涉及一种通过在
水和
乙醇的存在下将含
氟-18(18F)的盐与烷基卤化物或烷基
磺酸酯反应以获得高产率的18F-放射性药物的制备方法。该合成方法消除了使用有毒和/或环境不友好的有机溶剂的需求。
