Into 1600 g of acetic acid was dissolved 100 g (0.5 mole) of phenoxathiin, and 48.5 g (0.5 mole) of an aqueous hydrogen peroxide (35%) was added into it dropwise at room temperature. The mixture was agitated at room temperature for 7 days, and then added by 3,000 g of water to precipitate white crystals. They were collected by filtration and dried under reduced pressure to obtain the intended compound. The amount of the white crystals was 90 g and the yield was 83%.
