Reaction Steps

To a solution of 5 g (32.44 mmol) of 1-(2-fluoro-4-hydroxyphenyl)ethanone dissolved in 140 ml of anhydrous dioxane are added dropwise 5.7 g (35.68 mmol, 1.83 ml) of dibromine at 0° C. under argon. The reaction mixture is brought to 70° C. for 3 h. The solvent is concentrated by vacuum evaporation and the solid is recrystallized in 40 ml of 1,2-dichloroethane to yield 5.67 g (75%) of 2-bromo-1-(2-fluoro-4-hydroxyphenyl)ethanone in the form of a violet solid.
