摘要
索拉非尼是新型多激酶抑制剂,主要用于晚期肾细胞癌和不能切除的肝细胞癌的治疗。笔者以2-吡啶甲酸为原料,经氯化、醇解、酰胺化、与对氨基苯酚发生亲核取代反应得到中间体4-(4-氨基苯氧基)-2-(甲基氨甲酰基)吡啶,再与4-氯-3-三氟甲基苯异氰酸酯缩合得到索拉非尼。索拉非尼的总收率为55%(以2-吡啶甲酸计)。
Sorafenib is a new multi-kinase inhibitor approved for the treatment of advanced renal cell carcinoma and unresectable hepatocellular carcinoma.Sorafenib was synthesized from 4-chloro-3-(trifluoromethy1)phenyl isocyanate and 4-(4-aminophenoxy)-2-(methylcarbamoy1)pyridine,the later being obtained from 2-picolinic acid via chlorination,alcoholysis,amidation,nucleophilic substitution with 4-aminophenol.The overall yield of the title compound was 55% from 2-picolinic acid.
