A mixture of (3E)-6-fluoro-3-[4-(2-fluoropyridin-4-yl)-5,5-dimethylfuran-2(5H)-ylidene]-1,3-dihydro-2H-indol-2-one (50 mg, 0.15 mmol) and 2-(2-(piperazin-1-yl)ethoxy)ethanol (50 mg, 0.29 mmol) in 2 mL of DMSO was heated in 105° C. bath for 6 hours. The mixture was cooled to room temp and poured into 100 mL of water. The precipitates were filtered, washed with water and dried in vacuo to give (3E)-6-fluoro-3-[4-(2-{4-[2-(2-hydroxyethoxy)ethyl]piperazin-1-yl}pyridin-4-yl)-5,5-dimethylfuran-2(5H)-ylidene]-1,3-dihydro-2H-indol-2-one as a brown solid. Yield: 64 mg, 89%.
