An improved method for the synthesis of the anticancer drug picoplatin is provided. Condensation of a tetrachloroplatinate salt (TCP), such as potassium tetrachloroplatinate, and 2-picoline, in a solvent, is catalyzed by the presence of oxygen, such as in air, and additionally catalyzed by the presence of a Pt+4 complex, such as potassium hexachloroplatinate. The oxygen can be introduced into the reaction mixture by sparging, optionally with high shear mixing and under an inert gas headspace. The product trichloropicolineplatinate salt (TCPP) is a key intermediate in the synthesis of picoplatin, to which it can be converted by reaction of the TCPP with ammonia.
提供了一种改进的合成抗癌药物picoplatin的方法。在溶剂中,将四氯合铂酸盐(TCP),如四氯合铂酸钾,和2-吡啶缩合,通过氧气的存在,如空气中,催化,同时通过Pt+4络合物,如六氯合铂酸钾的存在也进行催化。氧气可以通过冲洗引入反应混合物中,可选地在高剪切混合和惰性气体头空间下进行。产物三氯吡啶铂酸盐(TCPP)是合成picoplatin的关键中间体,可以通过TCPP与氨的反应转化为picoplatin。
