The invention relates to N - ((5 - bromo thiophene - 2 - yl) sulfonyl) - 2, 4 - dichloro formamide synthetic method, which belongs to the technical field of organic synthesis. The method of the invention comprises the following steps: (1) weigh the raw materials according to the mixture ratio, and the 2, 4 - dichloro formic acid, 2 - bromo thiophene sulfonyl azide is added to the reactor, then sequentially added to the reactor in a small amount of acetonitrile solvent, butyl [...] distal of a cobalt catalyst and, in 60 - 90 °C stirring reaction under the condition of 2 - 6 the H; (2) after the reaction, the reaction product and concentration, sample, utilizing column chromatography separation, to obtain the target product III. The invention through one-step can be to obtain the target product, the synthetic method is simple, short reaction time, without the need for the inert atmosphere, low energy consumption, and the present invention the target product of the one-way yield can reach 76%, high conversion rate of raw materials. In addition, the method of the invention the reaction low equipment requirements, cobalt catalyst cheap raw materials are easy, the industrial cost is low. (by machine translation)
