4-(1H-imidazol-1-ylcarbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde (5.0 g, 23.0 mmol), 4-(2-aminoethyl)morpholine (4.5 g, 34.6 mmol), 5-fluorooxindole (3.47 g, 23.0 mmol), and THF (80 ml) were mixed and heated to 65° C. After stirring for 24 h at 65° C., the mixture was cooled to room temperature and filtered. The cake was washed with 40 ml THF and dried overnight at 50° C. under house vacuum. 5-[(Z)-(5-fluoro-2-oxo-1,2-dihydro-3H-indol-3-ylidene)methyl]-2,4-dimethyl-N-(2-morpholin-4-ylethyl)-1H-pyrrole-3-carboxamide (8.28 g) was obtained in 87% yield.
