Reaktionsschritte
For example, commercially available 2-aminotoluene-5-sulfonic acid was allowed to react with Villsmeyer reagent (N-(chloromethylene)-N-methylmethanaminium chloride), that is either commercially prepared or is generated in situ from a mixture of N,N-dimethylformamide and oxalyl chloride. The intermediate compound was then allowed to react with ammonium hydroxide in tetrahydrofuran to afford 4-amino-3-methylbenzenesulfonamide (Scheme IV).
