Reaction Steps
A solution of 1-(4-bromo-2-hydroxyphenyl)ethanone (1.06 g, 5 mmol) in dry N,N-dimethylformamide (10 mL) was charged with sodium hydride (240 mg, 10 mmol) and the mixture was stirred at room temperature for 30 minutes, then methyl 2-bromoacetate (0.84 g, 5.5 mmol) was added and the mixture was stirred at room temperature for 12 hours. After completed (40 mL) of methanol was added followed by concentrating under vacuum to give methyl 2-(2-acetyl-5-bromophenoxy)acetate (1.38 g, 90%) as colorless oil. 1H NMR (300 MHz, CD3OD) δ 8.01 (s, 1H), 7.65 (d, J=8.1 Hz, 1H), 7.18 (d, J=8.1 Hz, 1H), 6.97 (s, 1H), 4.73 (s, 2H), 3.81 (s, 3H), 2.69 (s, 3H).
