The invention relates to a process for the production of an 18F-labelled tracer which comprises treatment of a solid support-bound precursor of formula (I): SOLID SUPPORT-LINKER-I+ -TRACER (I) Y- wherein the TRACER is of formula (A): or an amine protected derivative thereof, wherein Y- is an anion, preferably trifluoromethylsulphonate (triflate) anion; and R1 is either (i) a group CH-NP1AP2A in which P1A and P2A are each independently hydrogen or a protecting group, or (ii) a carbonyl group; with 18F- to produce the labelled tracer of formula (II) or an amine protected derivative thereof, wherein R1 is as defined for the compound of formula (I).
本发明涉及一种制备18F标记示踪剂的方法,其中包括对式(I)的固体支持前体进行处理:SOLID SUPPORT-LINKER-I+ -TRACER (I) Y-,其中TRACER的式(A)为:或其氨基保护衍生物,其中Y-是阴离子,优选为三氟甲磺酸盐(三氟甲磺酸盐)阴离子;R1要么是(i)CH-NP1AP2A基团,其中P1A和P2A各自独立地是氢或保护基,要么是(ii)羰基基团;用18F-处理,以产生式(II)的标记示踪剂或其氨基保护衍生物,其中R1如式(I)化合物中所定义。
