実験手順

To 10 mL of 1,4-dioxane were added (3E)-3-(4-bromo-5,5-dimethylfuran-2(5H)-ylidene)-6-fluoro-1,3-dihydro-2H-indol-2-one (200 mg, 0.62 mmol), 6-fluoropyridin-3-ylboronic acid (104 mg, 0.74 mmol), PdCl2(PPh3)2 (22 mg, 0.031 mmol), 1M Na2CO3 aqueous solution (2.5 mL, 2.5 mmol). The mixture was heated at 88° C. under N2 for 2 hours, cooled to room temperature and poured into 100 mL of water. The precipitates were filtered, washed with water and dried to give the crude product. Purification of the crude product through silica gel column with 1-5% MeOH/CHCl3 afforded (3E)-6-fluoro-3-[4-(6-fluoropyridin-3-yl)-5,5-dimethylfuran-2(5H)-ylidene]-1,3-dihydro-2H-indol-2-one as a yellow solid. Yield: 100 mg, 47%.
