実験手順

To 3-((5-bromofuran-2-yl)methylene)-5-chloroindolin-2-one (150 mg, 0.466 mmol) in dioxane/water (2850/150 μL) was added 2-fluoro-4-(methoxycarbonyl)phenylboronic acid (111 mg, 0.559 mmol) and Cs2CO3 (456 mg, 1.398 mmol). The mixture was degassed with nitrogen for 5 minutes, then PdCl2 dppf (17 mg, 0.023 mmol) was added. The mixture was heated in microwave for 40 minutes at 110° C. Water was added and the solid formed was isolated by filtration to yield methyl 4-(5-((5-chloro-2-oxoindolin-3-ylidene)methyl)furan-2-yl)-3-fluorobenzoate. LCMS (M+1=398).
