摘要
4-氯-3-三氟甲基苯胺(5)和氯甲酸苯酯反应得到[4-氯-3-(三氟甲基)苯基]氨基甲酸苯酯(6),再和对氨基苯酚缩合得到N-[4-氯-3-(三氟甲基)苯基]-N-(4-羟基苯基)脲(7)。另用2-吡啶甲酸(2)经氯化、酰胺化得中间体N-甲基-(4-氯-2-吡啶基)甲酰胺(4)。4和7经亲核取代及成盐反应制得对甲苯磺酸索拉非尼,总收率约62%(以5计)。
N- [4-Chloro-3- (trifluoromethyl) pheny1] -N'- (4-hydroxyphenyl) urea (7) was prepared from 4-chloro- 3-(trifluoromethyl) aniline by reaction with phenyl chloroformate and condensation with 4-aminophenol. Meanwhile, N-methyl- (4-chloropyridin-2-yl) carboxamide (4) was prepared from 2-picolinic acid (2) by chlorination and amidation. Sorafenib tosylate was synthesized from 4 and 7 by condensation and salt formation with an overall yield of about 62 % [based on 4-chloro-3- (trifluoromethyl) aniline].
