A method for preparing nilotinib 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.
一种制备尼罗替尼的方法包括以下步骤: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基团进行脱保护处理,得到尼罗替尼,其中化合物A具有式I所示的结构,在式I中,R基团选自苄基、-COCF3、-CHO或-CO2R′,其中R′基团为C1˜C10烷基、C1˜C3烷氧基乙基或C7˜C19芳烷基。
