The invention discloses a synthesis method of 2-methyl pyrroline. The preparation method comprises the following steps: adding valeryl chloride and phthaloyl potassium salt into a high-boiling-point solvent and carrying out heating reflux for 5 to 15 hours; and S2, after the reaction liquid is cooled, filtering the reaction liquid, concentrating the reaction liquid, adding methanol for pulping toobtain a crude product, adding the crude product obtained in S1 into hydrochloric acid for heating reflux, after the reaction is completed, performing concentrating to dryness, adding water into residual liquid for dissolving, adjusting the pH value to be about 11 by using sodium carbonate, performing extracting for 3-5 times by using dichloromethane, and performing concentrating and drying, and distilling to obtain a product. According to the synthetic method of the 2-methyl pyrroline, disclosed by the invention, the used initial raw materials are easy to obtain, the preparation is convenient, the enlarged production is easy, the intermediate product is stable, and the collection efficiency is high.
