The invention provides a commercially practicable route to X[PtCl 3 (NH 3 )], where X represents an alkali metal ion, comprising the steps of heating a reaction mixture comprising cisplatin in an acidified organic solvent, together with NBu 4 OH, a Pt catalyst and saturated aqueous NaC1 solution to form (NBu 4 )[PtCl 3 (NH 3 )], and reacting that product with an alkali metal salt, to form X[PtCl 3 (NH 3 )] The product may be used in the synthesis of platinum anticancer complexes.
这项发明提供了一种商业上可行的制备X[PtCl 3 (NH 3 )]的途径,其中X代表一种碱
金属离子,包括以下步骤:在酸化有机溶剂中加热含有
顺铂的反应混合物,与NBu 4 OH、Pt催化剂和饱和的
氯化钠溶液一起形成(NBu 4 )[PtCl 3 (NH 3 )],然后将该产物与碱
金属盐反应,形成X[PtCl 3 (NH 3 )]。该产物可用于合成
铂抗癌配合物。
