Versuchsvorschrift

Add iodomethane (2.0 ml, 32.1 mmol) dropwise to a suspension of 4-bromo-2,6-difluorophenol (5.90 g, 28.2 mmol) and potassium carbonate (4.40 g, 31.8 mmol) in acetone (50 ml) at room temperature while stirring vigorously. Heat the mixture under reflux overnight. Evaporate acetone and add dichloromethane. Filter through silica eluting the product with dichloromethane/EtOAc. Concentrate to yield the title compound.
