To a solution of 6-bromo-1-((2-(trimethylsilyl)ethoxy)methyl)quinolin-2(1H)-one (1 g, 2.82 mmol) in toluene (20 mL) and water (20.00 mL) were added trivinylboraxin (0.684 g, 4.23 mmol), K2CO3 (0.780 g, 5.64 mmol). The reaction mixture was purged with N2 for 15 min, then Tetrakis (0.652 g, 0.564 mmol) was added and the reaction mixture was heated to 110° C. for 12 h. The reaction mixture was concentrated and dissolved in ethyl acetate and washed with water. The organic layer was dried over anhydrous sodium sulfate, and concentrated to get the 1-((2-(trimethylsilyl)ethoxy)methyl)-6-vinylquinolin-2(1H)-one (0.8 g, 94%), used without further purification. LCMS (ES-API), RT: 2.17 m/z 302.2 (M+H).
