実験手順: Bis(triphenylphosphine)palladium dichloride (PdCl2(PPh3)2) (0.6 g, 0.86 mmol), triphenylphosphine (0.44 g, 1.74 mmol), (2-acetylphenyl)boronic acid (6 g, 3.76 mmol) and tripotassium phosphate hydrate (16 g, 7.54 mmol) were placed in a flask. Nitrogen was blown into the flask and then the flask was filled with toluene (40 ml) and 4-chlorbenzonitrile (4 g, 2.90 mmol). The reaction mixture was stirred at 80° C. for 4 hours. The reaction mixture was cooled and washed with water. The organic layer was dried over sodium sulfate and then the solvent was evaporated. The product, 2′-acetyl-4-biphenylcarbonitrile (5a) was purified by a column (hexane/ethyl acetate=8/1). Yield: 3.3 g (51%). The reaction mixture was cooled washed with water The organic layer was dried over sodium sulfate the solvent was evaporated The product, 2′-acetyl-4-biphenylcarbonitrile (5a) was purified by a column (hexane/ethyl acetate=8/1)

実験手順: A mixture of tert-butyl 9-bromo-2,3-dihydro-1,4-benzoxazepine-4(5H)-carboxylate (200 mg, 0.605 mmol), a solution of 2-acetylphenylboronic acid (150 mg, 0.912 mmol) in ethanol (0.7 ml), 2N aqueous sodium carbonate solution (2.5 ml), and tetrakis(triphenylphosphine)palladium(0) (84.0 mg, 0.0730 mmol) in toluene (5 ml) was stirred under a nitrogen atmosphere at 95° C. for 12 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with water, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to give the desired product (190 mg, 85.6%) as an oil. the mixture was extracted with ethyl acetate The extract was washed with water dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure the residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1)
