반응 단계
To a solution of tert-butyl 4-bromo-2-methylbenzoate (2 g, 7 mmol) in dioxane/water (50 mL, 4:1) was added styrylboronic acid pinacol ester (1.64 g, 7 mmol), tetrakis(triphenylphosphine)palladium (0.7 mmol, 0.904 g), sodium carbonate (21 mmol, 2.3 g). The mixture was stirred at 90° C. under nitrogen gas atmosphere for 18 hours. LC-MS showed the start material has been consumed. Then evaporated the solvent and purified by column chromatography (silica gel, petroleum ether/ethyl acetate=30:1) to give tert-butyl 2-methyl-4-(1-phenylvinyl)benzoate (1.8 g, 91%).
