Method for preparing alpha-(4-isobutylphenyl)propionic acid or its precursor

A method for preparing α-(4-isobutylphenyl)propionic acid or its precursor is here disclosed which comprises a step (I) of dehydrogenating p-isobutylethylbenzene in a gaseous phase in the presence of a dehydrogenating metal catalyst to form p-isobutylstyrene and at least one unsaturated hydrocarbon compound selected from a group A defined in Claim 1; a step (II) of reacting p-isobutylstyrene obtained in the step (I) with carbon monoxide and hydrogen or with carbon monoxide and water or a lower alcohol in the presence of a transition metal complex carbonylating catalyst to form α-(4-isobutylphenyl)propionic acid or its precursor; and a step (III) of hydrogenating at least one unsaturated hydrocarbon compound selected from the group A obtained in the dehydrogenation step (I) to form p-isobutylethylbenzene, and recycling the thus formed p-isobutylethylbenzene through the step (I) as the raw material of the step (I).
