Isopropyl iodide → 4-Bromo-2-isopropoxy-1-methoxybenzene

Temperatur

20 °C

To a solution of 5-bromo-2-methoxyphenol (0.200 g, 1 mmol) in DMF (4 mL) was added potassium carbonate (0.209 g, 1.5 mmol) and isopropyliodide (120 μL, 1.2 mmol), the reaction mixture was stirred at room temperature (20° C.) for 3 h. After this time the crude reaction mixture was diluted with ethyl acetate (100 mL) and washed with water (2×100 mL). The organic layer was dried over magnesium sulfate, filtered and concentrated in vacuo to afford a yellow oil (200 mg, 0.81 mmol, 82%). No further purification was required.
