The invention relates to a process for the production of an [18F]fluorohaloalkane which comprises treatment of a solid support-bound precursor of formula (I): SOLID SUPPORT-LINKER-SO2—O—(CH2)nX (I) wherein n is an integer of from (1) to (7) and X is chloro, bromo or iodo; with 18F− to produce the [18F]fluorohaloalkane of formula (II) 18F—(CH2)n—X (II) wherein n and X are as defined for the compound of formula (I), optionally followed by (i) removal of excess 18F−, for example by ion-exchange chromatography; and/or (ii) removal of organic solvent.
本发明涉及一种制备[18F]
氟卤代烷的过程,包括将化合物(I)的固定支持前体进行处理:SOLID SU
PPORT-LINKER-SO2—O—(
CH2)nX (I),其中n为整数(1)至(7),X为
氯、
溴或
碘;使用18F-来制备化合物(II):18F—( )n—X (II),其中n和X与化合物(I)的定义相同,可选择性地跟随(i)去除多余的18F-,例如通过离子交换色谱;和/或(ii)去除有机溶剂。
