carboxylic acids and acyl chlorides. The preparation of the protonated form of [(18)F]-N-(2-fluoro-ethyl)-N-methylamine from the corresponding cyclic sulfamidate proceeded within a one pot two-step procedure (81 ± 12%, n = 10). The secondary amine reacted readily with acyl chlorides and/or carboxylic acids giving amides with yields ranging from 4 to 17% at the end of synthesis (182 ± 12 min). The new
我们研究了使用环状磺酰胺作为前体来产生仲胺作为随后与羧酸和酰氯反应的结构单元。[(18)F]-N-(2-氟-乙基)-N-甲胺的质子化形式从相应的环状磺胺酯的制备是在一锅两步程序中进行的 (81 ± 12%, n = 10 )。仲胺很容易与酰氯和/或羧酸反应生成酰胺,合成结束时(182±12 分钟)的产率为 4% 至 17%。新方法为分子标记提供了一种实用方法,其中在典型的放射性氟化条件下有利于前体的分子内环化。
