What this patent protects

本发明公开了一种晚期乳腺癌治疗药物艾拉司群中间体的制备方法:步骤1、6‑羟基‑3,4‑二氢‑1H‑2‑萘酮先进行羟基硅烷化保护,再与三甲基氯硅烷进行C‑C偶联对接反应,最后经脱保护得到中间体2‑(4‑甲氧基‑2‑硝基苯基)‑1,2,3,4‑四氢萘‑2,6‑二醇;步骤2、步骤1产物经脱羟基反应得到中间体6‑(4‑甲氧基‑2‑硝基苯基)‑5,6,7,8‑四氢萘‑2‑醇;步骤3、步骤2产物经硝基还原反应得到6‑(2‑氨基‑4‑甲氧基苯基)‑5,6,7,8‑四氢萘‑2‑醇。本发明所述艾拉司群新的合成方法,相对现有技术优势明显,反应完全,且副产物较少。
