N-4-(4-chlorophenyl)butyl-N,N-diethyl-7-[18F]fluoroheptylammonium ([18F]-fluoroclofilium) has been prepared as a potential cardiac imaging agent. For the synthesis of this radiolabelled ammonium salt, its tosyloxylated analogue was prepared as a precursor, and the non-radioactive fluorine analogue was synthesized as a reference compound. Radiofluorination was achieved by the treatment of N-4-(4-chlorophenyl)butyl-N,N-diethyl-7-(p-toluenesulfonyloxy)heptylammonium p-toluenesulfonate with 18F− in the presence of Kryptofix-2.2.2 in acetonitrile.

N-4-(4-氯苯基)丁基-N,N-二乙基-7-[18F]氟庚基铵([18F]-氟氯菲啶)已被制备为潜在的心脏成像剂。为了合成这种放射性标记的铵盐,其对甲苯磺酸酯化的类似物被制备为前体,而非放射性的氟类似物被合成作为参比化合物。通过在乙腈中使用Kryptofix-2.2.2的存在下,将N-4-(4-氯苯基)丁基-N,N-二乙基-7-(对甲苯磺酰氧基)庚基铵对甲苯磺酸盐与18F−反应,实现了放射性氟标记。版权所有 © 2003 John Wiley & Sons, Ltd.
