Reaction Steps

A solution of 3-((5-bromo-3-methylfuran-2-yl)methylene)indolin-2-one (125 mg, 0.41 mmol), 3-(methoxycarbonyl)phenylboronic acid (115 mg, 0.64 mmol), Cs2CO3 (270 mg, 0.83 mmol) and PdCl2(dppf) (16 mg, 0.02 mmol) in H2O/dioxane (5%, 5 mL) was heated at reflux for 1 h. The reaction mixture was diluted with H2O (150 mL) and extracted with EtOAc (3×100 mL). The organic layer was washed with brine (100 mL) and dried over Na2SO4 and concentrated to yield the desired methyl 3-(4-methyl-5-((2-oxoindolin-3-ylidene)methyl)furan-2-yl)benzoate. LCMS (ES): m/z 360 [M+1]+.
