実験手順

N-(3-Bromo-6-cyano-4-iodo-2-methoxy-5-methylphenyl)-2,2-dimethylpropionamide (I-6) (1.02 g, 2.26 mmol), 3-benzyloxybenzeneboronic acid (541 mg, 2.37 mmol), tripotassium phosphate (74-85%, 1.30 g, 4.52 mmol) and tetrakis(triphenylphosphine)palladium(0) (261 mg, 0.226 mmol) were added to a 50-ml eggplant-type flask, followed by purging with nitrogen. N,N-Dimethylformamide (20 ml) was injected into it with a syringe, followed by stirring at 95° C. for 4 hours. After cooling, the reaction liquid was diluted with ethyl acetate, successively washed with saturated brine (×3), 1 N hydrochloric acid, saturated brine, an aqueous saturated sodium hydrogencarbonate solution and saturated brine, dried on anhydrous magnesium sulfate, then the solvent was concentrated under reduced pressure to obtain a pale brown residue. The resulting residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=6:1) to obtain the entitled compound (630 mg, 55%) as a pale brown solid.
