The invention discloses a method for synthesizing 1,3-dibenzyl imidazoline-2-keto-cis-4,5-dicarboxylic acid, which comprises the following step b or step a to step b in a synthesis route: step a, reacting carbamide (II) with benzylamine (III), thus obtaining bibenzyl-ure (IV); and the step b, reacting the bibenzyl-ure (IV) with cis-2,3-dihalogenated succinic acid (V), thus obtaining the 1,3-dibenzyl imidazoline-2-keto-cis-4,5-dicarboxylic acid. The synthesizing method has the advantages of mild reaction conditions, high safety, simplicity and convenience for operation, easiness in purification processing of a final product, capability of leading HPLC (High Performance Liquid Chromatography) purity of a target product to be exceeded 99.5 percent, stable quality, easiness in obtaining raw materials, low price, high total recovery and the like, so that the total cost is greatly lowered, and the method is suitable for large-scale industrialization production requirements.
