Into a reactor, equipped with mechanical stirrer and thermometer, chlorosulfonic acid (17.49 g) and, slowly under stirring, N-formyl-phenothiazine (7.5 g) were charged, under nitrogen at 20° C. The reaction mixture was left under stirring at 20° C. for 3 hours. The HPLC analysis showed the formation of N-formyl-phenothiazine-2-sulfonic acid (75% yield).
