Potassium Hydroxide → 3-[3-(4-anilinoanilino)-3-oxopropyl]sulfanyl-N-(4-anilinophenyl)propanamide

Participants

Reaction Steps

To a suspension of 20.4 grams of N-4(anilinophenyl)acrylamide in 200 milliliters of ethanol was added 23.3 grams of N-(4-anilinophenyl)-3-mercaptopropionamide. A solution of one gram of potassium hydroxide in 10 milliliters of ethanol was added at 17.5°C. Within a few minutes the temperature began to rise, reaching a maximum of 28°C. Simultaneous with the increase in temperature, product began to precipitate. The reaction mixture was stirred for 2 hours. The solid product was filtered off and allowed to dry. There was obtained 41 grams (94 percent of theory) of product which melted at 199°-203°C.
