実験手順

Tetrakis(triphenylphosphine)palladium(0) (0.02 g, 0.02 mmol) was added to a solution of 3-(bromo-4-methoxybenzylidene)-1,3-dihydroindol-2-one (0.2 g, 0.61 mmol) in toluene (1 ml) and ethanol (1 ml), followed by addition of 2M aqueous sodium carbonate (1.2 ml, 2.4 mmol). To this mixture was added 3-ethoxyphenylboronic acid (0.11 g, 0.67 mmol), and the mixture was held at 100° C. in a sealed tube for 12 hours. The reaction mixture was added to water (40 ml) and extracted with ethyl acetate (75 ml). The combined organic layers were washed with saturated aqueous sodium bicarbonate (50 ml) and brine (50 ml). The organic layer was dried over magnesium sulfate and concentrated. The resulting solid was triturated with dichloromethane/hexanes to afford 0.9 g (39%) of 3-(3′-ethoxy-6-methoxybiphenyl-3-ylmethylene)-1,3-dihydroindol-2-one as a yellow solid.
