The invention relates to the preparation of fine chemical products, and particularly relates to a method for preparing 2-(4-fluorobenzene formyl) benzamide. The method is implemented by taking a 2-(4-fluorobenzene formyl) benzoic acid as a raw material through carrying out esterification reaction on the 2-(4-fluorobenzene formyl) benzoic acid and methanol firstly, and then carrying out ammonolysis reaction on the obtained product and aqua ammonia. According to the method, thionyl chlorides with large toxicity and irritation are abandoned, and therefore, the method is simple and practical, high in economical efficiency, good in yield, less in side reaction, and less in environmental pollution. |
