Procedure

To a solution of methyl 4-oxo-2-(phenylamino)-4,5-dihydrofuran-3-carboxylate (0.047 g, 0.20 mmol) which similarly prepared according to the procedure described in the Example 2, First step using methyl 4-chloroacetoacetate and phenyl isocyanate, and 7-azaindole-3-carboxaldehyde (0.029 g, 0.20 mmol) in 2-propanol (1.0 mL), piperidine (0.022 mL, 0.22 mmol) was added at ambient temperature. The mixture was refluxed for 5 days. Cooled to ambient temperature, the precipitate was collected by filtration, washed with ethanol and diisopropyl ether then dried to afford the titled compound as solid (0.031 g, y. 43%).
