Methods for the synthesis of the N-carbamoyl imidazole Formulae (I), (II) and its 1 :1 adduct with imidazole are provided. Methods for the preparation of these crystalline intermediates in a high state of purity are also provided. These intermediates react cleanly under mild conditions to produce sorafenib in high yield and purity, without generating difficult-to-remove impurities.
提供了合成N-氨基甲酰咪唑配方(I),(II)及其与咪唑的1:1加合物的方法。还提供了制备这些晶体中间体的高纯度方法。这些中间体在温和条件下干净地反应,产生高产率和纯度的索拉非尼,而不会产生难以去除的杂质。
