5-((tert-Butyldimethylsilyloxy)methyl)-2-fluoropyridin-3-ylboronic acid (0.400 g, 1.40 mmol) was placed into a flask with a mixture of DME/H2O (6 mL/2 mL). To the reaction mixture was added 5-bromo-2-(2,2,2-trifluoroethoxy)pyridine (0.358 g, 1.40 mmol), Na2CO3 (1.87 g, 17.6 mmol), and Pd(PPh3)4 (0.081 g, 0.07 mmol) and the reaction was allowed to stir at 80° C. overnight. The reaction was cooled to rt and concentrated. A solution of saturated NaHCO3 (5 mL) was added, and then this mixture was extracted with EtOAc (3×20 mL). The combined organic layer was then washed with saturated NaHCO3 (1×10 mL), brine (1×10 mL), dried (MgSO4), filtered, and concentrated. Purification by column chromatography (9:1 hexane:EtOAc) gave 5-((tert-butyldimethylsilyloxy)methyl)-2-fluoro-3-(6-(2,2,2-trifluoroethoxy)pyridin-3-yl)pyridine.
