A solvent containing 2 - amino -3 - methylbenzoic acid is stirred, N - methyl -3 - methyl -2 - amino - benzamide is dissolved in alkali liquor in a stirring reaction process, and reacted with NCS to obtain N - methyl -3 - methyl -2 - amino -5 - chloro - benzamide. The reaction of the bromination reaction, the oxidation reaction and the condensation reaction is carried out by cooperation of a catalyst so as to obtain chlorantraniliprole. By optimizing the preparation steps of chlorantraniliprole, the whole process is relatively simple in process steps, the post-treatment is simple, intermediate products can be obtained directly after the single step is finished, high environmental control requirements are not needed in the whole synthesis step, and industrialization can be conveniently realized.
