The invention belongs to the field of organic matter synthetic methods, and specifically relates to a synthetic method of an omega-substituted biuret compound. The synthetic method comprises the following steps: (1) condensation: adding substituted arylamine and potassium cyanate into a mixed solution of water and acetonitrile, warming, dropwise adding a part of acetic acid at the temperature of 45 to 100 DEG C, then adding remaining acetic acid 1 h later, and then reacting for 6 to 12 h; and (2) aftertreatment: carrying out recrystallization or column chromatography on an obtained product toobtain the omega-substituted biuret compound. The synthetic method overcomes the disadvantage that a nitrogen nitryl compound with dangerousness needs to be used in an existing synthetic process, anda one-pot method is adopted for replacing an existing two-step reaction with low yield.
