Reaction Steps
To a solution of 3-bromo-2-fluoropyridine (500 mg, 2.84 mmol) in anhydrous tetrahydrofuran (10 mL) under nitrogen was added potassium tert-butoxide (540 mg, 4.8 mmol) in portions over 30 minutes at 25° C., and stirring was continued for 4 hours at 25° C. The mixture was concentrated in vacuo and purified by silica gel flash chromatography eluting with dichloromethane/hexanes (50% to 100%) to give the title compound.
