Imatinib and its analogues were successfully synthesized by an improved method in 19.5– 46.2% total yield of six main steps. Pyrimidinyl amine was prepared by the reaction of enaminone and guanidine nitrate without the use of a toxic cyanamide. N-(2-Methyl-5-nitrophenyl)-4-(pyridin-3-yl) pyrimidin-2-amine as a key intermediate for the synthesis of imatinib was prepared by copper-catalyzed N-arylation
伊马替尼及其类似物通过改进的方法成功地合成了六个主要步骤,总收率为19.5–46.2%。嘧啶胺是通过烯胺酮和硝酸胍的反应制备的,无需使用有毒的氰胺。ñ - (2-甲基-5-硝基苯基)-4-(吡啶-3-基)嘧啶-2-胺,制备由铜催化的关键中间体为伊马替尼的合成ñ产率为82%的杂芳基胺-arylation 。在此C-N键形成反应中,使用铜盐代替了昂贵的钯化合物。使用水作为溶剂,通过N 2 H 4 ·H 2 O / FeCl 3 / C体系将中间体硝基化合物还原。
