Reaction Steps

4-(1-Acetyl-piperidine-4-carbonyl)-1,4,5,6,7,8-hexahydro-pyrrolo[3,2-b]azepine-2-carbaldehyde (56 mg) was condensed with 4-(3-fluoro-phenyl)-1,3-dihydro-indol-2-one (40 mg) and piperidine (2 drops) in ethanol (1 mL) at rt for overnight. The solvent was concentrated and the residue was purified on a silica gel column to give 50 mg of the title compound as a yellow solid.
