The disclosure provides a method for preparing nilotinib. The preparation method includes the following steps: performing an aminocarbonylation reaction on a compound A and 3-(4-methyl-1H-imidazole-1-yl)-5-(trifluoromethyl) aniline to obtain an amination product; and performing deprotection treatment of an R group on the amination product to obtain the nilotinib, wherein the compound A has a structure shown in formula I, and in formula I, an R group is selected from benzyl, -COCF3, -CHO or -CO2R', where an R' group is C1∼C10 alkyl, C1∼C3 alkoxy ethyl or C7∼C19 aralkyl. The preparation method is short in synthesis route and mild in reaction condition. Moreover, with adoption of a special raw material, the preparation method may improve a yield of the nilotinib and simultaneously reduce process cost.
本公开提供了一种尼洛替尼的制备方法。该制备方法包括以下步骤:对化合物 A 和 3-(4-甲基-1H-咪唑-1-基)-5-(三氟甲基)苯胺进行氨基化反应,得到氨基化产物;对胺化产物上的R基进行脱保护处理,得到尼罗替尼,其中化合物A的结构如式I所示,式I中R基选自苄基、-COCF3、-CHO或-CO2R',其中R'基为C1∼C10烷基、C1∼C3烷氧基乙基或C7∼C19芳烷基。该制备方法合成路线短,反应条件温和。此外,该制备方法采用特殊原料,可提高尼洛替尼的收率,同时降低工艺成本。
