The invention discloses a method for synthesizing 4-methyl catechol. The method comprises the steps of carrying out acylation reaction on p-cresol as a starting materia to obtain p-cresyl acetate, carrying out Fries rearrangement reaction in a high-boiling-point inert solvent to obtained 2-hydroxy-5-methyl acetophenone, alkalifying, forming a salt, oxidizing at a low temperature, after the reaction is completed, reducing the reaction solution, acidifying, extracting and concentrating to obtain a crude product and distilling the crude product to obtain the pure 4-methyl catechol. The method disclosed by the invention is environmental friendly, available in raw materials, mild reaction conditions, low requirements on equipment, simple operation, low production cost, less side effects and high yield and is suitable for industrial production.
