Versuchsvorschrift

A mixture of 4-hydroxybenzoic acid (1.38 g, 0.01 mol), 2-chloro-N,N-diethylacetamide (1.4 g, 0.01 mol) triethylamine (1.44 ml. 0.01 mol) and sodium iodide (150 mg, 0.001 mol) in N,N-dimethylformamide (6 ml) was stirred at room temperature for 18 h. Water (100 ml) was added and the mixture allowed to stand at 4° C. for 5 h. The title compound was isolated by filtration, washed with water and recrystallized from ethanol-water to give 1.8 g. Mp 148°-149° C.
