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.
