Versuchsvorschrift

To a solution of 40 g of 2-acetylaminomethylthiophene and 30.3 g of acetylchloride in 600 ml of dichloroethane is added a small portion of 76.3 g of anhydrous aluminum chloride under cooling at 5°-10° C. After the mixture is stirred at 10° C. for 30 minutes and poured into ice-cold water, the precipitated crystals are collected by filtration to give 2-acetylaminomethyl-5-acetylthiophene, melting F- at 129°-130° C.
