Preparing 2-(substituted phenyl)propionic acids by heating a mixture containing succinic acid anhydride with a 2-(2-oxo-3-cyclohexenyl)propionic acid derivative and then recovering the 2-(2-substituted phenyl)propionic acid derivative from the reaction mixture. The heated mixture can also contain other acids such as an 2-(1-carboxy-2-oxo-3-cyclohexenyl)propionic acid.
通过加热含有琥珀酸酐和2-(2-氧代-3-环己烯基)丙酸衍生物的混合物来制备2-(取代苯基)丙酸,然后从反应混合物中回收2-(2-取代苯基)丙酸衍生物。加热的混合物还可以含有其他酸,如2-(1-羧基-2-氧代-3-环己烯基)丙酸。
