Reaction Steps
A quantity of 3.7 g of 3-hydroxy-2,4-difluoro-bromobenzene is dissolved in 25 ml of acetone and 2.5 g of potassium carbonate is added followed by 2.2 ml of methyl iodide. The mixture is stirred at 20° C. for 6 hours and the solvent evaporated. After addition of dichloromethane, the suspension is filtered. Evaporation of the solvent affords the desired product.
