Reaction Steps

Add 2-chloropyridin-4-amine (500 mg, 3.9 mmol), 1,2-difluoro-4-nitrobenzene (620 mg, 3.9 mmol), Cs2CO3 (3.2 g, 9.8 mmol) to DMF (15 mL). Stir the reaction at 110° C. for 16 hrs. Cool to room temperature, add water (100 mL), extract with EtOAc (15 mL×3). Combine the organic layers and wash with brine, dry over anhydrous Na2SO4. Concentrate under reduced pressure to give the crude product. Purification by chromatography (silica gel, EtOAc:PE=1:4) affords the title compound (280 mg, 27%). MS: (M+1): 268.1.
