Description

抗肿瘤药物AP26113的制备方法 技术领域
本发明属于有机合成路线设计及其原料药和中间体制备技术领域,特别涉及一种抗肿瘤药物AP26113的制备方法。
背景技术
AP26113是由Ariad制药公司开发的一种靶向小分子酪氨酸激酶抑制剂的试验性药物,用于治疗对克唑替尼(Crizotinib)耐药的间变性淋巴瘤激酶阳性(ALK)转移性非小细胞肺癌(NSCLC)患者。该药于2014年8月被美国FDA授予突破性治疗药物资格。目前的临床数据显示,AP26113对ALK阳性的非小细胞肺癌患者,包括脑转移患者,均有持续性抗肿瘤活性。而且对ALK的抑制活性是克唑替尼的10倍左右,可抑制全9种已鉴定的克唑替尼耐药性ALK突变。
AP26113的化学名为:5-氯-N2-[4-[4-(二甲基氨基)-1-哌啶基]-2-甲氧基苯基]-N4-[2-(二甲基亚膦酰)苯基]-2,4-嘧啶二胺(I),其结构式为:
Figure PCTCN2016090408-appb-000001
AP26113的制备方法已有研究报道,Ariad公司的PCT专利WO2009143389和美国专利US20130225527、US20130225528和US20140066406报道了AP26113及其原料A和B的制备方法。该方法是通过2,4,5-三氯嘧啶依次与原料A和B发生嘧啶环上的取代反应制备得到目标化合物AP26113。
Figure PCTCN2016090408-appb-000002
分析上述合成路线,虽然合成步骤比较简单,但是由于2,4,5-三氯嘧啶上的三个氯原子的亲核活性相差有限,在面对相同或相似的苯胺类基团时,其位置选择性必然会产 生干扰,产生不必要的副反应,从而影响产品的质量。同时,反应过程中对于贵金属钯试剂的使用也使制造成本有所增加,不利于实现其产业化。
所以,如何运用现代合成技术,采用易得原料,设计和开发出简易快捷、经济环保和便于工业化的新合成路线,尤其是客服嘧啶环上位置选择性所带来的副反应,对于该药物的经济技术发展具有重要意义。
发明内容
本发明的目的在于针对现有技术中的缺陷,设计出一条逐步引入官能团,从而避免副反应发生的新型合成路线。通过该合成路线所形成的AP26113的制备方法,具有原料易得、副反应少、经济环保且适合工业化生产等优点。
