摘 要:1-环丙基-1,3-二氢咪唑并[4,5-C]吡啶-2-酮是人类呼吸道合胞病毒(RSV)抑制剂BMS-433771的关键中间体,以此为基础可以合成一系列氮杂双咪唑酮类RSV抑制剂。以4-羟基吡啶为原料,经硝化、氯化和亲核取代反应、氢化、环化4步反应得到1-环丙基-1,3-二氢咪唑并[4,5-C]吡啶-2-酮,其结构经1H NMR表征确证。该合成工艺操作简单,杂质少,具有工业化应用前景。

Abstract:1-Cyclopropyl-1,3-dihydroimidazolo[4,5-C]pyridinone-2-one is a key intermediate of human respiratory syncytial virus (RSV) inhibitor BMS-433771, on the basis of thisintermediate a series of azodiimidazolidone RSV inhibitors can be synthesized. Using 4-hydroxypyridine as the raw material, 1-cyclopropyl-1,3-dihydroimidazolo [4,5-C]pyridinone-2-one was obtained by nitration, one pot reaction of chlorination and nucleophilic substitution, hydrogenation and cyclization, the structure of the final product was confirmed by 1H NMR. The synthetic process is easy to operate with less impurities, so it is suitable for industrial production.
Key words:azabimidazolone; RSV inhibitor; 4-hydroxypyridine; BMS-433771
