Reaction Steps

To a solution of 4-hydroxyacetophenone (2.5 g, 18.3 mmol) (Aldrich) in dioxane (10 mL) was added dropwise a solution of bromine (3.22 g, 20.1 mmol) in dioxane (20 mL). After stirring for 10 minutes, the mixture was concentrated in vacuo and the residue was recrystalized from methanol to provide 2-bromo-1-(4-hydroxyphenyl)ethanone (1.73 g, 44% yield).
