Preparation of Sulfaquinoxaline: Using o-phenylenediamine as raw material. Firstly, o-phenylenediamine reacts with sodium cyanide, formaldehyde in acidic media to obtain N-cyanomethyl-o-phenylenediamine. Secondly, the cyclization of N-cyanomethyl-o-phenylenediamine and potassium hydroxide to generate 2-amino-3,4-dihydro-yl. Thirdly, using hydrogen peroxide to dehydrogenize in the presence of ferrous chloride to get 2-amino-quinoxaline. Finally, after condensation and hydrolysis with acetylsulfanilyl chloride
sulfonamides, we can get the product.
Uses of Sulfaquinoxaline: It is a veterinary medicine which can be given to cattle and sheep to treat coccidiosis. It is also used as an animal-specific broad-spectrum antimicrobial agent, which is more toxic to mammals.
