Versuchsvorschrift

To a solution of 5.0 g of 2-acetylaminomethylthiophene and 4.4 g of chloroacetylchloride in 100 ml of dichloromethane is added a small portion of 8.6 g of anhydrous aluminum chloride at room temperature, and the mixture is refluxed with stirring for an hour and poured into ice-cold water. The precipitated crystals are collected by filtration to give 2-acetylaminomethyl-5-chloroacetylthiophene, melting at 146°-148° C.
