Prepare the required drugs first, including benzene compounds with specific substitutions, reagents containing sulfonic acid groups, etc., all of which need pure products to ensure a smooth reaction. The reaction starts, in a suitable reactor, according to the precise ratio, the phenyl compound containing phenylamino group and the phenyl compound containing (2-sulfophenyl) amino group are added, and an appropriate amount of alkali is added as a catalyst to assist the reaction. Dissolve in an organic solvent to mix the substances evenly. Control the temperature of the kettle and slowly raise the temperature to a certain degree, such as between 60 and 80 degrees Celsius. At this temperature, continue to stir to make the molecules fully collide and react.
After the first step of reaction is completed, cool down to room temperature, continue to add the reagent that can form the cyclohexadiene structure, adjust the temperature again to a suitable range, such as 50 to 70 degrees Celsius, and stir the reaction again. In this process, closely observe the reaction process, which can be monitored by thin-layer chromatography and other methods. When the reaction is almost complete, pour the reaction liquid into ice water and let the product precipitate. By filtration, a solid crude product is obtained.
The crude product still contains impurities and needs to be refined. A mixture of alcohol and water is used as a solvent to recrystallize. The crude product is dissolved by heating, filtered hot to remove insoluble impurities, and the filtrate is left to cool, and the product is then crystallized.
