A new process of producing a 2-(4-alkylphenyl)-propionic acid known as a valuable anti-inflammatory agent is now provided, which comprises treating an alkyl 3-methyl-3-(4-alkylphenyl)-glycidate with an acid to produce 2-(4-alkylphenyl)-propionaldehyde and 3-methyl-3-(4-alkylphenyl)-pyruvic acid through a new reaction, and then oxidising these intermediate products to the desired 2-(4-alkylphenyl)-propionic acid. This new process is operable in a facile way, gives a high yield of the desired product and is suitable for a commercial practice.
