In the present invention, a synthesis method of Imatinib is disclosed, which comprises the following steps: the Imatinib, namely 4-(4-methyl-piperazin-1-ylmethyl)-N-[4-methyl-3-[4-(3-pyridinyl)-pyrimidin-2-ylamino]-benzamide shown in formula (III), is formed by reacting 4-methyl-N-3-(4-pyridin-3-yl-pyrimidin-2-yl)-1,3-benzenediamine shown in formula (I) with 4-(4-methyl-piperazin-1-methyl)-benzoic ester shown in formula (II), under the action of a base and in a non-protonic organic solvent,
in the above generic chemical structural formula, R represents aliphatic alkyl having 1-10 carbon, phenyl, substituted phenyl, benzyl or substituted benzyl. The present invention provides a new synthesis method of Imatinib, which is formed under mild reaction conditions, and is environmentally friendly with a high-yield.
本发明揭示了一种伊马替尼的合成方法,包括以下步骤:在非质子有机溶剂中,在碱的作用下,通过将式(I)所示的4-甲基-N-3-(4-吡啶-3-基-嘧啶-2-基)-1,3-苯二胺与式(II)所示的4-(4-甲基哌嗪-1-基)-苯甲酸酯反应,形成式(III)所示的伊马替尼,即4-(4-甲基哌嗪-1-基甲基)-N-[4-甲基-3-[4-(3-吡啶基)-嘧啶-2-基氨基]-苯甲酰胺。在上述通用化学结构式中,R代表具有1-10个碳的脂肪烷基,苯基,取代苯基,苯甲基或取代苯甲基。本发明提供了一种新的伊马替尼合成方法,反应条件温和,环保且产率高。
