First, the choice of starting materials is crucial. Or choose a naphthalene derivative containing a specific substituent, such as a suitable hydroxyl group, an amino group and a sulfonic acid group, which is the basis for building the target compound. First, the naphthalene derivative is diazotized with an aromatic amine containing acetamido and trifluoromethyl under specific conditions. Diazotization requires careful control of reaction temperature, pH and reactant ratio. Usually in a low temperature and acidic environment, aromatic amines interact with sodium nitrite to form diazonium salts.

Then, the resulting diazonium salt is coupled to the naphthalene derivative. This coupling reaction also requires precise control of conditions to ensure the accuracy of the coupling check point. The polarity of the reaction medium, temperature and the choice of catalyst all affect the progress of the reaction and the yield of the product.

Second, there is another synthesis route, which is to protect or modify the sulfonic acid group, hydroxyl group and amino group of the cyclonaphthalene first to prevent unnecessary side reactions in subsequent reactions. After the key azo bond is formed, the protecting group is selectively removed to obtain the target compound.

During the synthesis process, each step of the reaction needs to be carefully monitored, and the reaction process and product purity can be confirmed by means of thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). The structure identification of the intermediate and final products is also indispensable. The molecular structure and functional group characteristics can be analyzed in detail by spectroscopy techniques such as nuclear magnetic resonance (NMR), infrared spectroscopy (IR) and mass spectrometry (MS), so as to ensure that the resulting product is sodium-5- [4-acetamido-2- (trifluoromethyl) phenyl] azo] -6-amino-4-hydroxynaphthalene-2-sulfonate.
