Direct H–D exchange reactions were applied to the preparations of stable isotope-labeled TKI258 and two TKI258 metabolites. Each compound was made in one single H–D exchange reaction with excellent isotope incorporation. The number of deuterium incorporation and deuterium distribution in the molecules was similar in all three compounds. Stable isotope-labeled TKI258 was also prepared from d8-methylpiperazine in a multistep synthesis.
直接 H-D 交换反应用于制备稳定同位素标记的 TKI258 和两种 TKI258 代谢物。每种化合物都是通过一次 H-D 交换反应制备的,同位素掺入效果极佳。这三种化合物的掺入
氘的数量和
氘在分子中的分布相似。稳定同位素标记的 TKI258 也是通过多步合成法从 d8-甲基
哌嗪中制备出来的。
