The application provides a preparation method of a benzaldehyde aniline compound and relates to the technical field of organic synthesis. The preparation method provided by the application comprises the following steps: in a solvent, with an alkali as a promoter, under an atmosphere with an oxygen concentration of 20v100%, the temperature of a reaction system is controlled to be 50-70 DEG C, a diphenyl ketone compound I is reacted with an aniline compound II to generate a benzaldehyde aniline compound III, and the reaction product is subjected to column chromatography separation to obtain a pure benzaldehyde aniline compound III. The method has the beneficial effects that the reaction is simple, green and environment-friendly, the use of an expensive transition metal catalyst is avoided, the reaction condition is mild and controllable, and an environment-friendly byproduct is generated.
