A mixture of 10-methylacridin-9(10H)-one (4.2 g, 20 mmole) and chlorosulfonic acid (100 mL, 1.5 mole) was heated at reflux for 5 hours. Reaction mixture was then condensed, cooled down to room temperature and poured carefully on 500 g of ice. The yellow precipitate of product was collected by filtration, washed with water and dried to provide 8.1 g of the title compound. This material was used for next step without purification.
