  • Synthesis of [2H5]-ebastine fumarate and [2H5]-hydroxyebastine
    作者:Zhoujie Yu、Wei Wang、Liqin Chen
    DOI:10.1002/jlcr.1877
    日期:2011.6.15
    This study describes the synthesis of deuterium-labelled ebastine fumarate and its deuterium-labelled metabolite hydroxyebastine. The synthesis of the two desired compounds both used [2H5]-bromodiphenylmethane as deuterium-labelled reagent, which was synthesized beforehand in three steps. [2H5]-ebastine was synthesized in further three steps with a 27% overall yield and [2H5]-hydroxyebastine was synthesized in further seven steps with a 13% overall yield.

  • The synthesis of fexofenadine
    作者:Wang Ronggeng、Zhao Yougui、Zhang Guanchao
    DOI:10.1007/s11164-012-0747-y
    日期:2013.5
    This work proposes a new simple route for fexofenadine synthesis with low cost and easily obtainable raw materials. We use benzene and methallyl as starting reactants, applying steps of Friedel–Crafts alkylation reaction, hydrolysis, oxidation, esterification reaction, and reduction reaction to obtain the intermediate product, followed by N-alkylation reaction to obtain 4-1-hydroxy-4-[4-(hydroxydiphenyl)-piperidine]butyl}-α,α-dimethylbenzene acetate. Then, the final product fexofenadine is obtained upon hydrolysis. In the synthesis process, we constantly optimize the reaction conditions such as reaction time, reaction temperature, solvent selection, and other factors, thus improving the final yield of the target product fexofenadine to 33.51 %.
    本研究提出了一条利用低成本、易获取的原材料合成非索非那定的新的简单路线。我们以苯和甲基烯丙基为起始反应物,通过弗里德尔-卡夫斯烷基化反应、解、氧化、酯化反应和还原反应等步骤得到中间产物,然后通过 N-烷基化反应得到 4-1-羟基-4-[4-(羟基二苯基)-哌啶]丁基}-α,α-二甲基苯乙酸酯。然后经解得到最终产品非索非那定。在合成过程中,我们不断优化反应时间、反应温度、溶剂选择等反应条件,从而将目标产物非索非那定的最终收率提高到 33.51%。
