Abstract
本发明提供了一种氧嗪酸钾的制备方法,具体包括以下步骤:首先在室温条件下,将1‑脲基间二氮杂茂烷二酮(式Ⅳ)、碱和碘化钾溶解于纯化水中,然后将反应液降温,分批加入N‑卤代酰胺,加入完毕后升温进行反应。反应结束后,将反应液降温,用酸调节pH,搅拌养晶后进行抽滤,滤饼用冷纯化水洗涤至无色,再用冷无水醇类溶剂淋洗,最后真空干燥得到氧嗪酸钾。与现有技术相比,本发明的方法具有原料易得、操作简便、反应条件温和、质量稳定、收率高、对环境无污染等优点,适合工业化生产。
Description
技术领域
本发明涉及一种一种氧嗪酸钾的制备方法,属于化学合成技术领域。
背景技术
本发明涉及的化合物是氧嗪酸钾(Potassium oxonate),又名氧嗪酸钾,化学名:1,4,5,6-四氢-4,6-二氧-1,3,5-三嗪-2-羧酸钾。氧嗪酸钾是口服抗癌复方药物替吉奥胶囊中的三种活性药物之一。替吉奥胶囊是一种氟尿嘧啶衍生物的口服抗癌剂,主要由替加氟和两种生化调节剂吉美嘧啶、奥替拉西钾组成。其中,替加氟具有优良的口服生物利用度,能在体内转化为5-氟尿嘧啶;吉美嘧啶可抑制5-氟尿嘧啶的降解,使其在血浆和肿瘤组织中保持稳定的血药浓度,从而增强抗肿瘤活性;氧嗪酸钾通过抑制嘧啶转磷酸核糖基酶来降低5-氟尿嘧啶在胃肠道的毒性及不良反应。两种生化调节剂共同作用,使患者体内能够维持较高的5-氟尿嘧啶血药浓度,提高抗肿瘤活性,同时降低药物的消化道毒性。
发明内容
本发明旨在提供一种操作简单、反应条件温和、产品收率高、纯度高、污染少,适于工业化生产的氧嗪酸钾的制备方法。
具体实施方式
以下实施例进一步说明本发明,实施例仅用于说明本发明而不对其构成限制。根据本发明的方法,对本发明的改进均属于本发明的保护范围。
实施例
在20L的玻璃反应釜中,加入乙醛酸溶液(质量浓度为50%)1.4kg,尿素1.8kg,反应液缓慢升温至80℃-90℃,搅拌反应8小时后降至室温。过滤去除催化剂颗粒后,反应液减压浓缩,加入异丙醚重结晶,得到1-脲基间二氮杂茂烷二酮(式Ⅳ)1.56kg,收率66.6%。
实施例
在室温避光条件下,向反应瓶中加入1-脲基间二氮杂茂烷二酮(式Ⅳ)(10.00g,63.29mmol)、氢氧化钾(24.81g, 443.03mmol)、碘化钾(0.42g, 2.53mmol)和纯化水(100mL),待固体溶解后,反应液冷却至0℃。分批加入NBS(13.52g, 75.95mmol),加入完毕后,控温20~25℃反应3小时,降温至0~5℃,用冰醋酸调节pH至5.5,搅拌养晶2小时,抽滤,滤饼用冷纯化水洗涤至无色,再用冷无水乙醇(20mL)洗涤,50℃真空干燥,得到氧嗪酸钾,收率91.32%,HPLC检测纯度为99.968%。
