Reaction Steps

Methyl 2,6-difluoro-5-(trimethylsilyl)nicotinate (1.19 g, 4.85 mmol), 4-bromo-2-iodophenol (1.450 g, 4.85 mmol), and silver trifluoromethanesulfonate (1.496 g, 5.82 mmol) were dissolved in dry THF (40 mL) and treated with potassium carbonate (1.006 g, 7.28 mmol). The mixture was heated to 60° C. for 10 hours before being cooled to rt and filtered through a pad of celite. Water (100 mL) and diethyl ether (100 mL) were added to the filtrate and the phases were separated. The organics were dried with magnesium sulfate, filtered and evaporated to dryness under reduced pressure. Purification using silica chromatography (hexane to DCM gradient) gave the desired methyl 2-(4-bromo-2-iodophenoxy)-6-fluoro-5-(trimethylsilyl)nicotinate.
