Procedure

A stirred solution of 3-methyl-5-(2-morpholin-4-yl-ethyl)-4-oxo-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine-2-carbaldehyde (52 mg, 0.15 mmol), 5-fluoro-1,3-dihydro-indol-2-one (25 mg, 0.4 mmol) in 0.4 ml of ethanol was added dropwise with anhydrous piperidine (0.04 ml). The mixture was stirred at room temperature overnight. The precipitate was filtered under reduced pressure. The resulting solid was washed with anhydrous ethanol (0.2 ml×5), purified by silica gel column chromatography with dichloromethane:methanol (10:1) as eluents to give 2-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-3-methyl-5-(2-morpholin-4-yl-ethyl)-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one (30 mg, 38%) as a yellow solid.
