摘 要:以邻乙基苯胺为原料经硝化、环合、甲基化、硝基还原、取代、甲基化等反应制得2,3-二甲基-N-(2-氯嘧啶-4-基)-N-甲基-2H-吲唑-6-胺(7);中间体 7 与5-氨基-2-甲基苯磺酰胺(8)缩合、成盐制得目标产物盐酸帕唑帕尼(1)。笔者对帕唑帕尼的合成工艺进行了改进,总收率38.1%,其结构经ESI-MS、1H NMR确证。改进后的合成工艺成本低廉,操作简单,反应时间短,适合工业化生产。

Abstract:Pazopanib hydrochloride was prepared from 2-ethylaniline via nitration,cyclization,methylation,reduction,substitution and methylation to give the intermediate compound,2,3-dimethyl-N-(2-chloropyrimidin-4-yl)-N-methyl-2H-indazol-6-amine,which was condensed with 2-methyl-5-aminobenzene sulfonamide and then salified to afford the target compound with an overall yield of 38.1%. Its structure was confirmed by 1H NMR and ESI-MS. This improved process is suitable for industrial production since it has lots of advantages,such as low cost,simple operation and short reaction time.
