2-Methyl-2-[[(7-methyl-7H-benzo[c]carbazol-10-yl)methyl]amino]-1,3-propanediol (1, 7U85) was synthesized as the mesylate salt in the [14C]-labelled form with specific activity 48.4 mCi/mmol suitable for metabolism and tissue distribution studies in animals The synthetic sequence involved the regiospecific synthesis of a bromobenzo[c]carbazole by a modified Fischer indole synthesis, formylation by a Bouveault reaction, and reductive amination. The radiochemical purity was > 97.3%.
2-甲基-2-[[(7-甲基-7H-苯并[c]咔唑-10-基)甲基]氨基]-1,3-丙二醇(1,7U85)以甲磺酸盐形式被合成,并标记为[14C]放射性同位素形式,比活度为48.4 mCi/mmol,适合进行动物的代谢和组织分布研究。合成步骤包括通过改良的费歇尔吲哚合成法进行位点特异性的溴代苯并[c]咔唑合成、布韦罗反应进行甲酰化以及还原胺化步骤。放射化学纯度大于97.3%。
