実験手順
A mixture of 6-chloro-N*2*-(4-chloro-phenyl)-pyrimidine-2,4-diamine (0.077 g, 0.30 mmol), 5-chloro-2-methoxy-phenyl boronic acid (0.112 g, 0.60 mmol), palladium (II) acetate (0.017 g, 0.075 mmol), 2-(dicyclohexylphosphino)biphenyl (0.105 g, 0.30 mmol) and potassium phosphate (0.254 g, 1.2 mmol) in dry toluene (3.5 ml) was heated at 90-100° C. under an argon atmosphere for 18 hours. After cooling to room temperature, ether (20 ml) was added and the mixture was washed with aqueous sodium hydroxide solution (1.0 M, 10 ml), with saturated aqueous sodium chloride solution (10 ml), and dried over magnesium sulfate. After concentrating under reduced pressure, the residue was purified by flash chromatography on silica gel eluting with ethyl acetate-hexane (1:3) to provide the title compound (0.032 g, 30% yield) as a white powder.
