The invention relates to a method for producing 2,5-dimethylphenyl acetic acid by reacting p-xylol with chloroacetyl chloride to form 2-chloro-1-(2,5-dimethylphenyl) ethanone, which reacts with the compound of formula (II) to form the compound of formula (III). The latter is then rearranged into a mixture of compounds (IV) and (V), which is then saponified to form 2,5-dimethylphenyl acetic acid. (II) (III) (IV) (V). |
