Reaction Steps
The crude ethyl (2-acetyl-4-bromophenoxy)acetate was dissolved in ethanol (5 mL). A 2 mol/L aqueous solution of sodium hydroxide (5 mL) was added to the solution, and the mixture was stirred at room temperature for 1 hr. The reaction mixture was made acidic with the addition of 2 mol/L hydrochloric acid (7 mL), and then ethyl acetate and brine were added. The organic layer was separated, washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was recrystallized from ethyl acetate and n-hexane to afford the title compound (0.85 g).
