Disclosed is a method for synthesizing sapropterin dihydrochloride. The present disclosure reduces a synthesis route of the sapropterin dihydrochloride, and resolves a racemate intermediate or an intermediate having a low antimer isomerism value by using a chiral resolving reagent, thereby obtaining an intermediate having a high antimer isomerism value. Raw materials are cheap and readily available, and the cost is significantly reduced, hence providing an effective scheme for mass industrial production of the sapropterin dihydrochloride.
