Reaction Steps

(R)-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 1f (200 g, 0.623 mmol), 5-fluoro-1,3-dihydro-indol-2-one (84.67 mg, 0.56 mmol) and piperidine (30.8 μL, 0.31 mmol) were dissolved in 1.09 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 system was allowed to cool down to room temperature to precipitate solids. The resulting solids were filtered to give the title compound (R,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 1 (256 mg, 90%) as a yellow solid.
