摘要
(R)-1-苯基-1,2-乙二醇与对甲苯磺酰氯经取代反应得到(R)-1-苯基-1,2-羟基-对甲苯磺酸酯,再与对硝基苯乙胺在碳酸钾作用下得到(R)-2-((4-硝基苯乙基氨基)-1-苯乙醇,最后通过还原铁粉催化硝基还原、与2-氨基噻唑-4-乙酸胺酯缩合得到米拉贝隆,总收率为58%.
(R)-2-hydroxy-2-phenylethyl 4-methylbenzenesulfonate was synthesized by the displacement reaction of(R)-1-phenylethane-1,2-diol with 4-toluene sulfonyl chloride,which was reacted with 4-Nitrophenethylamine to afford(R)-2-((4-nitrophenethyl)amino)-1-phenylethanol in the presence of K2CO3.Finally,the intermediate products was reduced by Iron powders and condensation with 2-(2-aminothiazol-4-yl)acetic acid to produce Mirabegron in 58%total yield.
