Reaction Steps
A solution of chromium trioxide (1.50 g) in water (4.0 ml) was added to 2-methylthioxanthone-10,10-dioxide (1.29 g) in acetic acid (25 ml). Sulphuric acid (2.0 ml) was added and the mixture was boiled under reflux for 15 min. The mixture was cooled, and the crystallised product was filtered off, washed with water, and dried at 110° C, m.p. 276° C.
