摘 要:以鄰乙基苯胺為原料經(jīng)硝化、環(huán)合、甲基化、硝基還原、取代、甲基化等反應制得2,3-二甲基-N-(2-氯嘧啶-4-基)-N-甲基-2H-吲唑-6-胺(7);中間體 7 與5-氨基-2-甲基苯磺酰胺(8)縮合、成鹽制得目標產(chǎn)物鹽酸帕唑帕尼(1)。筆者對帕唑帕尼的合成工藝進(jìn)行了改進(jìn),總收率38.1%,其結構經(jīng)ESI-MS、1H NMR確證。改進(jìn)后的合成工藝成本低廉,操作簡(jiǎn)單,反應時(shí)間短,適合工業(yè)化生產(chǎn)。 |

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. |
Key words:antineplastic agent;pazopanib;synthesis;procedure improvement |
