A mixture of 2-mercaptoethanol (1.66 g, 0.02 mol), anhydrous sodium acetate (2 g) and 4-chloro-3-nitrobenzenesulfonamide (2.37 g, 0.01 mol) was heated on the steam bath for about 5 hours. The reaction mixture was diluted with water, acidified with 6N hydrochloric acid and cooled. Filtration and drying gave 2.11 g of a yellow solid that was recrystallized from ethyl acetate, m.p. 150°-152° C.
