Procedure
In a 1-liter egg plant-type flask, methyl iodide (6.67 mL, 105 mmol) was added to a DMF (200 mL) solution of methyl 4-bromo-3-hydroxy-5-{[(trifluoromethyl)sulfonyl]oxy}benzoate (19.9 g) and potassium carbonate (14.5 g, 105 mmol), and stirred at room temperature for 4 hours. The reaction solution was diluted with ethyl acetate, washed with water and saturated saline water, dried with sodium sulfate, filtered, and concentrated to obtain a crude product. This was purified through silica gel column chromatography (Biotage [SiO2, 40+M]) with a hexane/ethyl acetate developer system to obtain the title compound as a colorless solid.
