Versuchsvorschrift

5.0 g of 7-hydroxy-3,4-dimethylcoumarin were dissolved in 20 ml of H2O/1.1 g of NaOH at room temperature, while stirring, and 3.4 g of ethanesulfonyl chloride were added. The mixture was stirred overnight, and the precipitate was filtered off under suction and recrystallized from ethanol.
