Cesium carbonate → HCID 67994323, compound

Participants

Reaction Steps

A solution of 1-nitro-2-naphthylamine (875 mg, 4.65 mmol), 3-bromobenzonitrile (846 mg, 4.65 mmol), cesium carbonate (3.03 g, 9.30 mmol), tris(dibenzylidene-acetone)dipalladium(0) (213 mg, 0.23 mmol) and (+/−)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (217 mg, 0.35 mmol) in tolunene (10 mL) was heated at 110° C. for 16 hours. The reaction mixture was poured into a saturated aqueous sodium bicarbonate solution, and was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1), to give the titled compound (503 mg, yield 37%).
