The synthesis of β3-adrenergic receptor agonists A and B with radiolabeled amide fragment, required for drug disposition studies, was accomplished based on initial formation of 2-(4-(2-amino-2-methylpropyl)phenoxy)-5-[14C]-cyanopyridine by the reaction of 2-bromo-5-iodopyridine with para-substituted phenol, and following cyanation of aromatic iodide with potassium cyanide-[14C]. After the coupling
β3-肾上腺素能受体激动剂 A 和 B 与药物处置研究所需的放射性标记酰胺片段的合成是基于 2-(4-(2-氨基-2-甲基丙基)苯氧基)-5-[14C ]-氰基吡啶通过 2-溴-5-碘吡啶与对位取代苯酚反应,然后用氰化钾-[14C] 将芳香碘化物氰化。生成的胺与 4-羟基吲哚和 4-羟基咔唑的缩水甘油衍生物偶联后,相应的腈用碱性过氧化氢水解得到目标酰胺 A 和 B。 版权所有 © 2006 John Wiley & Sons, Ltd.
