Reaction Steps

To a solution of 1-amino-5-ethylsulfonyl-2-hydroxybenzene (20.13 g, 100.0 mmol, 1.0 equiv) in ethanol (200 mL) were added carbon disulfide (190.0 g, 150 mL, 2494 mmol, 25.0 equiv) and potassium hydroxide (6.73 g, 120 mmol, 1.2 equiv) and the reaction mixture heated to reflux over night. The solvent was evaporated, the residue treated with 1 M hydrochloric acid, extracted with ethyl acetate (3×150 mL) and the combined organic fractions dried over MgSO4. Evaporation of the organic solvent gave the crude product which was recrystallized from ethyl acetate to yield the title compound as yellowish solid. MS (ISN): 242.4 [M−H]−.
