Reaction Steps

To a solution of 7-azaindole-3-carboxaldehyde (0.10 g, 0.70 mmol) and ethyl 4-oxo-2-(phenylamino)-4,5-dihydrofuran-3-carboxylate (0.18 g, 0.70 mmol) in ethanol (3.0 mL), piperidine (0.083 mL, 0.84 mmol) was added at ambient temperature. The mixture was refluxed for 12 h. Cooled to ambient temperature, the precipitate was collected by filtration, washed with cold ethanol and isopropyl ether then dried to afford the titled compound (0.13 g, y. 48%).
