The present invention relates to method for the preparation of a 18F-labeled aniline derivative of the general formula I
by fluorination of an aniline derivative with [18F]fluoride under the application of microwave heating, wherein X is a leaving group; R1 and R2, independently of one another, are H, alkyl, alkenyl, alkinyl, aryl, heteroaryl and alkylaryl, and wherein R1 and R2 can be joined together to form a ring structure; and Y represents one or more substituents selected from the group consisting of H, alkyl, alkenyl, alkinyl, aryl, heteroaryl and alkylaryl, halogen, fused aryl and fused heteroaryl. Further, the invention relates to 18F-labeled compounds of the above given formula and the use thereof in non-invasive imaging of a mammal, preferably a human, by positron emission tomography, especially for obtaining information on the extend, kinetics or treatment response of a disease related to pathological proteins in the central nervous system.
本发明涉及一种制备18F标记的苯胺衍生物的方法,其通式为I,通过在微波加热下使用[18F]氟化物对苯胺衍生物进行氟化,其中X是一个离去基团;R1和R2独立地为H,烷基,烯基,炔基,芳基,杂芳基和烷基芳基,其中R1和R2可以结合形成环状结构;Y代表从H,烷基,烯基,炔基,芳基,杂芳基和烷基芳基,卤素,融合芳基和融合杂芳基中选择的一个或多个取代基。此外,本发明涉及上述给定式的18F标记化合物及其在哺乳动物,特别是人体的正电子发射断层扫描中的非侵入性成像中的使用,尤其是用于获取与中枢神经系统中病理蛋白质相关的疾病的范围、动力学或治疗反应的信息。
