4-(1H-imidazol-1-ylcarbonyl)-3,5-dimethyl-1H-pyrrole-2-carbaldehyde (11.3 g, 51.9 mmol), 4-morpholinopiperidine (15.0 g, 88.2 mmol), 5-fluorooxindole (7.84 g, 51.9 mmol), and THF (126 ml) were mixed and heated to 66° C. After stirring for 68 h at 66° C., the mixture was cooled to room temperature and filtered. The cake was washed with 4×20 ml THF and dried overnight at 70° C. under house vacuum. (3Z)-3-({3,5-dimethyl-4-[(4-morpholin-4-ylpiperidin-1-yl)carbonyl]-1H-pyrrol-2-yl}methylene)-5-fluoro-1,3-dihydro-2H-indol-2-one 16.09 g was obtained in 68% yield.
