The synthesis is described of aminophenpyramine (7) (N‐5‐[2‐(4‐aminophenyl)ethananmido]pentanyl}‐N′‐(4‐methoxybenzyl)‐N‐methyl‐N′‐(2‐pyridinyl)‐1,2‐ethandiamine), its monoiodo‐ and diiodo‐derivatives (8 and 9), and iodoazidophenpyramine (1). The last compound is synthesised by two different routes to confirm the identity of the [125I]iodinated ligand previously made only in solution and used for characterisation
氨基苯吡胺 (7) (N-5-[2-(4-氨基苯基) 乙氨基]戊基}-N'-(4-甲氧基苄基)-N-甲基-N'-(2-吡啶基)-的合成描述1,2-乙二胺)、其单碘-和二碘-衍生物(8和9)和碘代叠氮苯吡胺(1)。最后一个化合物是通过两种不同的途径合成的,以确认以前仅在溶液中制备的 [125I] 碘化配体的身份,并用于表征组胺 H1 受体蛋白。该程序使用了新型中间体 4-氨基-3-碘-苯乙酸 (11) 和 4-叠氮基-3-碘-苯乙酸 (13)。它们对合成非放射性碘化光亲和受体配体具有普遍适用性,这可能是相应放射性标记化合物的化学鉴定所必需的。
