Procedure

To a solution of ethyl 4-oxo-2-pyrrolidinyl-4,5-dihydrofuran-3-carboxylate (0.034 g, 0.15 mmol) which similarly prepared according to the procedure described in the Example 4, First step and 7-azaindole-3-carboxaldehyde (0.022 g, 0.15 mmol) in ethanol (1.0 mL), 2M hydrochloric acid in ethanol (0.16 mL, 0.32 mmol) was added at ambient temperature. The mixture was refluxed for 3 h. Cooled to ambient temperature, the precipitate was collected by filtration, washed with ethanol and diisopropyl ether then dried to afford the titled compound (0.038 g, y. 61%).
