100 mmol 1-amino-5-ethylsulfonyl-2-hydroxybenzene were dissolved in 200 ml of ethanol and 150 ml of carbon disulfide. 120 mmol of potassium hydroxide was added and the mixture refluxed over night. The solvent was evaporated, the residue treated with 1 M hydrochloric acid, extracted with ethyl acetate and dried. Evaporation gave the crude product which was recrystallized from ethyl acetate to yield the title compound as yellowish solid.
