(S)-5-(2-Hydroxy-3-morpholin-4-yl-propyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-1 H-pyrrolo[3,2-c]pyridine-2-carbaldehyde 5f (40 mg, 0.125 mmol) was dissolved in 2 mL of ethanol under stirring at room temperature, and N-(5-fluoro-2-oxo-2,3-dihydro-1H-indol-6-yl)-2-hydroxy-acetamide 9f (25.1 mg, 0.112 mmol) was then added to the solution. Upon completion of the addition, the mixture was stirred until all dissolved, and piperidine (50 μL, 0.5 mmol) was then added to the reaction solution. Upon completion of the addition, 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 system was naturally cooled down to room temperature to precipitate solids. The resulting solids were filtered to give the title compound (S,Z)-N-{5-fluoro-3-[5-(2-hydroxy-3-morpholin-4-yl-propyl)-3-methyl-4-oxo-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridin-2-ylmethylene]-2-oxo-2,3-dihydro-1H-indol-6-yl}-2-hydroxy-acetamide 9 (51 mg, yield 80%) as a yellow solid.
