1.
Etaconazole was synthesized by bromating 2,4-dichloroacetophenone with Br2,and then dehydratingbetween the resulted ω-Bromo-2,4-dichloroacetophenone and 1,2-butanediol with p-toluenesulfonic acid as catalyst,followed by condensation the obtained 2-(2,4-dichlorophenyl) -2-bromomethyl-4-ethyl-1,3-dioxolane with 1,2,4-triazoleNa salt.
将2,4-二氯苯乙酮与溴发生取代反应生成ω-溴-2,4-二氯苯乙酮,然后在催化剂对甲基苯磺酸存在下,ω-溴-2,4-二氯苯乙酮与1,2-丁二醇发生脱水反应得到2-(2,4-二氯苯基)-2-溴甲基-4-乙基-1,3-二氧戊环,最后缩酮化合物与三氮唑钠缩合得到乙环唑。
