Procedure

(S)-5-(2-Hydroxy-3-morpholin-4-yl-propyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine-2-carbaldehyde 5f (490 mg, 1.53 mmol), 5-fluoro-1,3-dihydro-indol-2-one (219 mg, 1.45 mmol) and piperidine (100 μL, 1.0 mmol) were dissolved in 5 mL of ethanol under stirring at room temperature. The reaction system was stirred at 80° C. in an oil bath in dark for 2 hours. The reaction was completed until TLC showed the disappearance of starting materials, and the oil bath was removed. The reaction mixture was naturally cooled down to room temperature to precipitate solids. The resulting solids were filtered to give the title compound (S,Z)-2-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-5-(2-hydroxy-3-morpholin-4-yl-propyl)-3-methyl-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one 5 (460 mg, 69.9%) as a yellow solid.
