Reaction Conditions

Reaction Steps

A mixture of methyl 3-bromobenzoate (5.87 g, 27.3 mmol), aniline (3.73 mL, 41.0 mmol), cesium carbonate (12.5 g, 38.2 mmol), tris(dibenzylidenacetone)dipalladium (0) (1.0 g, 1.09 mmol), rac-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (1.02 g, 1.64 mmol) and toluene (60 mL) was stirred under a nitrogen atmosphere at 80° C. for 16 hrs. The reaction mixture was cooled, washed with water and saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-4/1) to give the title compound (2.13 g, yield 34%) as pale-yellow crystalsitle compound.
