| titleOfInvention | Process for producing 4-azidosulfonylphthalic anhydride |
| abstract | The present disclosure provides a process for the production of 4-azidosulfonylphthalic anhydride. In an embodiment, a process is provided and includes chlorinating 4-sulfophthalic acid trisodium salt (1), under solvent reaction conditions, to form a dissolved 4-chlorosulfonylphthalic anhydride (2) and an insoluble sodium chloride. The process includes first removing the insoluble sodium chloride from the dissolved 4-chlorosulfonylphthalic anhydride to form an isolated 4-chlorosulfonylphthalic anhydride. The process includes reacting, under solvent reaction conditions, the isolated 4-chlorosulfonylphthalic anhydride with sodium azide to form a dissolved 4-azidosulfonylphthalic anhydride and an insoluble sodium chloride. The process includes second removing the insoluble sodium chloride from the dissolved 4-azidosulfonylphthalic anhydride to form an isolated 4-azidosulfonylphthalic anhydride. The process includes retrieving a solid 4-azidosulfonylphthalic anhydride (3) from the isolated 4-azidosulfonylphthalic anhydride. |
