The present invention relates to the field of radiopharmaceuticals for in vivo imaging, in particular to precursors for the preparation of 18F-labelled tau imaging radiotracers. The invention provides alternative methods of preparation of such precursors, with fewer process steps. Also provided are protected quinoline intermediates useful in the synthesis, and methods of 18F-radiofluorination using precursors prepared via the method of the invention.
本发明涉及体内成像放射性药物领域,特别是用于制备18F标记的tau成像放射性示踪剂的前体。本发明提供了制备这种前体的替代方法,步骤更少。还提供了在合成中有用的受保护的喹啉中间体,以及使用通过本发明方法制备的前体的18F-放射性氟化方法。
