How is 4- (2-Naphthalenylamino) Benzenesulfonic Acid synthesized?

To prepare 4 - (2 - naphthalene amino) benzenesulfonic acid, the method is as follows:
First take the naphthalene, so that it is co-heated with concentrated nitric acid to obtain 2 - nitronaphthalene. This step requires temperature control, and the reaction should not be too strong. 2 - Naphthalene is more active, and iron powder and hydrochloric acid are used as reducing agents to reduce it to 2 - naphthalene amine. This reduction process requires attention to the reaction conditions to make the reaction complete.
Take another benzenesulfonic acid, mix the obtained 2 - naphthalene amine with benzenesulfonic acid, catalyze with an appropriate catalyst, and heat for condensation reaction. During the reaction, pay close attention to the temperature and reaction process, and adjust it in a timely manner to make the amino group of 2-naphthylamine and the specific position of benzenesulfonic acid condensate, and finally obtain 4- (2-naphthalene amino) benzenesulfonic acid.
During the entire synthesis process, the reaction conditions at each step are crucial. From the ratio of raw materials, the temperature of the reaction, and even the amount of catalyst, fine regulation is required to obtain a product with higher yield and purity.
