実験手順: An oven dried resealable Schlenk tube was evacuated and backfilled with argon and charged with palladium acetate (2.2 mg, 0.01 mmol, 1.0 mol %), 2-(di-tert-butylphosphino)biphenyl (6.0 mg, 0.020 mmol, 2.0 mol %), phenylboron dihydroxide (183 mg. 1.5 mmol), and potassium fluoride (174 mg, 3.0 mmol). The tube was evacuated and backfilled with argon, and THF (1 mL) and 2-chlorobenzyl cyanide (152 mg, 1.0 mmol) were added through a rubber septum. The tube was sealed with a teflon screwcap, and the reaction mixture was stirred at room temperature until the starting aryl chloride had been completely consumed as judged by GC analysis. The reaction mixture was then diluted with ether (30 mL) and poured into a separatory funnel. The mixture was washed with 1.0 M NaOH (20 mL), and the aqueous layer was extracted with ether (20 mL). The combined organic layers were washed with brine (20 mL), dried over anhydrous magnesium sulfate, filtered, and concentrated. The crude material was purified by flash chromatography on silica gel to afford 178 mg (92%) of the title compound.

実験手順: 2-(Bromomethyl)biphenyl (1.35 g, 5.48 mmol), potassium cyanide (368 mg, 5.65 mmol), and a catalytic amount of 18-crown-6 ether were added to acetonitrile (10 ml), and the mixture was heated under reflux for 5 days. The reaction mixture was added with water and extracted with ethyl acetate. The extract was washed with saturated aqueous sodium bicarbonate solution and saturated brine, and dried over magnesium sulfate. Insoluble solids were removed by filtration, and the filtrate was concentrated under reduced pressure. The resulting oil was purified by silica gel column chromatography (ethyl acetate-hexane) to obtain the title compound as colorless solid (1.07 g, yield: quantitative). the mixture was heated under reflux for 5 days extracted with ethyl acetate The extract was washed with saturated aqueous sodium bicarbonate solution and saturated brine dried over magnesium sulfate Insoluble solids were removed by filtration the filtrate was concentrated under reduced pressure The resulting oil was purified by silica gel column chromatography (ethyl acetate-hexane)
