摘要
以3-氨基-4-甲基苯甲酸甲酯(2)为原料,采用一锅法,首先与氰胺发生反应,再与(E)-3-二甲胺基-1-(3-吡啶基)-2-丙烯-1-酮(5)环合,再经皂化,得到关键中间体4-甲基-3-[[4-(3-吡啶基)-2-嘧啶基]氨基]苯甲酸(7),7经酰氯化后与3-(4-甲基-1H-咪唑基)-5-三氟甲基苯胺(10)缩合得到尼洛替尼,总收率32%(以2计)。
4-Methyl-3- [ (4-pyridin-3-yl-pyrimidin-2-yl) amino~ benzoic acid (7) was obtained in one-pot process, by the reaction of methyl 3-amino-4-methylbenzoate (2) with cyanamide followed by cyclization with (E) -3- dimethylamino-l-pyridin-3-yl-propenone (5), and then hydrolysis. Finally nilotinib was synthesized by acyl-chloration of 7 and condensation with 3- (4-methyl-lH-imidazol-l-yl) -5- (trifluoromethyl) aniline (10) with an overall yield of 32 % based on 2.
