摘　　要：目的改进芳香化酶抑制剂阿那曲唑的合成工艺。方法以3,5-二甲基苯甲酸为起始原料,经过酯化、溴化、氰化、甲基化、还原、氯代、N-烷基化和去氨基化合成阿那曲唑。结果产物结构经1H-NMR和MS确证。八步反应的总收率为24.2%。结论改进后的合成方法操作简便,适合工业化生产。Objective To improve the synthetic procedure of aromatase inhibitor-anastrozole. Methods Using 3, 5-dimethylbenzoic acid as the starting material, anastrozole was obtained via eight reaction steps, including esterification, bromination, cyanidation, methylation, reduction, chlorination, N-alkylation and deamination. Results The total yield was 24.2 %. The structure of final product was confirmed by the analysis of ^1HNMR and MS. Conclusions Compared with the patent method, the improved process is convenient to operate with lower cost and higher yield and is more suitable for the production in large scale.
