Synthesis
The general procedure for synthesizing 2-amino-5-iodobenzotrifluoride from 1-(trifluoromethyl)-1,2-phenyliodonyl-3(1H)-one and p-iodoaniline is as follows: in this embodiment, p-iodoaniline was used as the aromatic amine, and the rest of the reaction conditions and post-processing steps were the same as in Example 28. The specific reaction conditions were as follows: 1-(trifluoromethyl)-1,2-phenyliodono-3(1H)-one (0.5 mmol, 1.0 eq.), p-iodoaniline (1.5 mmol, 3.0 eq.), nickel hydroxide (10 μmol), and potassium carbonate (1.5 mmol, 3.0 eq.) were used as bases, and DMSO (2 mL) was used as a solvent, and the temperature of the reaction was 35 °C. The reaction time was 2 hours. After the reaction was completed, post-treatment was carried out according to the method of Example 1.
