The invention relates to a bromethalin synthesizing production process, and relates to the technical field of chemical engineering. According to the invention, 2,4-dinitro-N-phenyl-6-(trifluoromethyl) is obtained through a coupling reaction. 2,4-dinitro-N-phenyl-6-(trifluoromethyl) is used as a raw material and is subject to a methylation reaction, such that N-methyl-2,4-dinitro-N-phenyl-6-(trifluoromethyl)aniline is obtained. N-methyl-2,4-dinitro-N-phenyl-6-(trifluoromethyl)aniline is used as a raw material, and a bromination reaction is carried out, such that N-methyl-2,4-dinitro-N-(2,4 dibromobenzene)-6-(trifluoromethyl)aniline is obtained. Secondary bromination is carried out, such that bromethalin is obtained. The process provided by the invention has the advantages that bromethalin is convenient and simple to prepare; the process is environment-friendly and is pollution-free; the raw materials are easy to obtain; equipment investment is low; product purity is high; the process is convenient to operate;
