Procedure

In a 1-liter egg plant-type flask, cesium carbonate (24.8 g, 76.3 mmol) was added to a DME (200 mL) solution of methyl 4-bromo-3,5-bis{[(trifluoromethyl)sulfonyl]oxy}benzoate (26.0 g), and stirred at 60° C. for 3 hours. DME was removed under reduced pressure, the residue was diluted with ethyl acetate, washed with water and saturated saline water in that order, dried with sodium sulfate, filtered and concentrated to obtain a crude product as a brown solid. This was washed with a mixed solvent of toluene and hexane to obtain the title compound as a colorless solid.
