Take 2-methoxyaniline first and make it react with succinic anhydride in a suitable reaction environment to obtain 1 - [ (2-methoxyphenyl) amino] -1,3 -dioxidine-2 -acid. This reaction needs to be controlled by temperature and time, so that the two can fully react to obtain a higher yield.
Then the obtained 1- [ (2-methoxyphenyl) amino] -1,3-dioxodine-2-acid is diazotized in an acidic environment with suitable diazotizing reagents, such as sodium nitrite, to obtain the corresponding diazonium salt. In this process, the type, concentration, and reaction temperature of the acid need to be precisely controlled to avoid the decomposition of the diazonium salt.
Take another 3-amino-4-sulfobenzoic acid and couple it with the above diazonium salt to form 2 - {4- [ (E) - {1- [ (2-methoxyphenyl) amino] -1,3-dioxydino-2-yl} diazenyl] -3 -sulfobenzoic acid}.
