Vorschrift

A mixture of 2-bromo-1-(2,3-dihydrobenzo[1,4]dioxin-6-yl)ethanone (1.03 g, 4.00 mmol), 4-nitrophenol (0.57 g, 4.00 mmol), and cesium carbonate (1.63 g, 5.00 mmol) in dry N,N-dimethylformamide (10 mL) was stirred at room temperature for 1 hour. The reaction mixture was diluted with cold water. The resultant solid was collected by filtration gave the title compound (1.19 g, 94%). The product was used in the next step without purification.
