Versuchsvorschrift

4-Chlorothiophene-3-carbonyl chloride (13.5 g, 0.075 mol) are dissolved in 30 ml of dioxane and the solution is added dropwise at room temperature to a solution of aniline (7.7 g, 0.083 mol) in pyridine (160 ml). Stirring is carried out for 12 hours at room temperature, after which the mixture is evaporated to dryness and the residue is taken up in dichloromethane. The organic phase is extracted with aqueous citric acid solution, sodium bicarbonate solution and water, dried and evaporated to dryness. Yield: 16.7 g, 94%; mp. 119° to 121° C.
