The invention discloses a method for synthesizing 4-ethyl-4-hydroxyl-1,7-dihydro-tetrahydro-pyrane[3,4-c] pyridine-3,8-ketone. The method is to take derivatives of nicotinic acid as initial raw materials; the derivatives of the nicotinic acid react with a lithium reagent, are subjected to nucleophilic reaction with butanone acid amide and subjected to quenching to obtain a lactone intermediate compound; pyridine rings are subjected to hydrolysis to generate a pyridinone compound; lactone rings are reduced to a menthandiol compound; and amide is subjected to hydrolysis and ring closing reaction to obtain the 4-ethyl-4-hydroxyl-1,7-dihydro-tetrahydro-pyrane[3,4-c] pyridine-3,8-ketone. The method has the advantages of short reaction process, high yield, simple and cheap synthetic raw materials, easy purification and the like, particularly can obtain products with high purity without column chromatography, and can completely meet the demands of industrialized production.
