Reaction Steps

In a 4 mL screw cap vial fitted with a small egg-shaped stir bar, were combined 5-fluoro-2-(4-fluoro-2-hydroxybenzoylamino)-N-(5-chloropyridin-2-yl)benzamide (200 mg, 0.49 mmol) and powdered anhydrous K2CO3 (103 mg, 0.74 mmol, 1.5 eq) in 0.5 mL of dry dimethylformamide (DMF). Ethyl iodide (115 mg, 0.74 mmol) was then added, the vial was capped, and the slurry heated to 50° C. with vigorous stirring overnight. The slurry was diluted with 20 mL water and extracted into 15 mL of dichloromethane. The organic layer was then washed with 20 mL portions of saturated NaHCO3, water, and brine; then dried over Na2SO4 and concentrated in vacuo. The residue was dissolved in a few mL of dichloromethane and purified by radial chromatography, eluting using hexanes, then 4:1 hexanes:EtOAc, to provide 135 mg (63%) of the title compound as pinkish-white crystals.
