Reaction Steps

1-(4-hydroxy-3-methoxyphenyl)ethanone (25.0 g, 0.15 mol) and potassium carbonate (15.4 g, 0.11 mol) were added to DMF (80 mL). 4-bromo-1-(bromomethyl)-2-fluorobenzene (50.2 g, 0.19 mol) was added to the mixture, and the mixture was stirred at room temperature for 2 hours and then stirred at 60° C. for 16 hours. Methanol (40 mL) was added to this reaction solution, which was stirred at 60° C. for 1 hour and then blended with water (200 mL). The precipitated crystals were filtered and washed with water and hexane. The crystals were vacuum-dried at 60° C. for 3 hours, yielding 1-[4-(4-bromo-2-fluorobenzyloxy)-3-methoxyphenyl]ethanone (52.7 g).
