Method preparing aromatic primary amine compound from phenol type compound

The invention belongs to the field of organic synthesis, and aims to provide a method preparing aromatic primary amine compound from phenol type compound. The method includes the following steps: phenol type compound and ammoniation reagents are solved in organic solvent or mixed solvent of the organic solvent and cosolvent, alkali is added, reaction is conducted for 2-4 hours under 50-80 DEG C, temperature rises to 100-160 DEG C, stirring reaction is conducted for 2-24 hours, and aromatic primary amine type compound is obtained after postprocessing. Alternatively, part of alkali is added, reaction is conducted for 2-24 hours under 50-80 DEG C, another part of alkali is additionally added, temperature rises to 100-160 DEG C, stirring reaction is conducted for 2-24 hours, and the aromatic primary amine compound is obtained. The reaction system of the method enables phenolic hydroxyl to be directly converted into amino, reaction steps are reduced, three-waste discharge is effectively reduced, the aromatic primary amine compound can be directly combined by utilizing low-content alkali, and the application range of substrate is wide. The method is strong in generality and high in yield.
