To a suspension of 200 grams of N-(4-anilinophenyl)acrylamide in 2450 milliliters of ethanol was added 64.8 grams of 2-mercaptoethyl sulfide. A solution of 5 grams of potassium hydroxide in 50 milliliters of ethanol was then added at 20°C. Within 5 minutes the temperature began to rise, reaching a maximum of 31°C. after about 15 minutes. As the temperature began to rise, product began to precipitate. The reaction mixture was stirred for 1 hour and the solid product was then filtered off and allowed to dry. There was obtained 231.7 grams (87.5 percent of theory) of product which melted at 195.5° to 197.5°C.
