摘 要:丙二酸环异丙酯依次与原甲酸三乙酯和对溴苯胺缩合、环合、硝化、氯代生成3-硝基-4-氯-6-溴喹啉(7)。对硝基苯乙腈与碘甲烷经烷基化、还原生成2-(4-氨基苯基)-2-甲基丙腈(10),与7发生取代反应,得到2-[4-[(6-溴-3-硝基喹啉-4-基)氨基]苯基]-2-甲基丙腈,再经还原、环合、甲基化、Suzuki偶联反应制得PI3K/m TOR双重抑制剂NVP-BEZ235,总收率为6%(以丙二酸环异丙酯计算),纯度为99.1%,并经~1H NMR、MS确证结构。该路线原料价廉易得、操作简便、反应条件温和,适合较大规模制备。6-Bromo-4-chloro-3-nitroquinoline(7) was synthesized from 2,2-dimethyl-1,3-dioxane-4,6-dione by substitution with triethoxymethane, condensation with 4-bromoaniline, cyclization, nitrification and chlorination. NVP-BEZ235, the PI3K/mTOR inhibitor, was synthesized from 2-(4-nitrophenyl)acetonitrile via alkylation with iodomethane and reduction to give 2-(4-aminophenyl)-2-methylpropanenitrile(10), followed by substitution with 7 to obtain 2-[4-[(6-bromo-3-nitroquinolin-4-yl)amino]phenyl]-2-methylpropanenitrile, which was subjected to reduction, cyclization, alkylation and Suzuki-coupling reaction with an overall yield of 6%(based on 2,2-dimethyl-1,3-dioxane-4,6-dione) and purity of 99.1%. The structure of the target product was confirmed by ~1H NMR and MS. This method started with cheap raw materials was of simple experimental operation and mild reaction conditions. It was suitable for largescale pilot study.
