Reaction Steps

A pressure tube was charged with (3E)-3-(4-bromo-5,5-dimethylfuran-2(5H)-ylidene)-6-fluoro-1,3-dihydro-2H-indol-2-one (60 mg, 0.19 mmol), morpholine (48 mg, 0.56 mmol), Mo(CO)6 (49 mg, 0.19 mmol), palladium(II) acetate (4.0 mg, 0.018 mmol), DBU (85 mg, 0.56 mmol) and anhydrous THF (3 mL). The tube was immediately capped under nitrogen and heated in 108° C. bath for 1 hour. After cooling, the reaction mixture was filtered through a short celite pad. The filtrate was concentrated and purified by silica gel flash chromatography (5-10% MeOH in CHCl3) to give (3E)-3-[5,5-dimethyl-4-(morpholin-4-ylcarbonyl)furan-2(5H)-ylidene]-6-fluoro-1,3-dihydro-2H-indol-2-one as a yellow solid. Yield: 39 mg, 55%.
