Procedure

To a solution of ethyl 2-(benzo[d]thiazol-6-ylamino)-4-oxo-4,5-dihydrofuran-3-carboxylate (0.070 g, 0.23 mmol) which similarly prepared according to the procedure described in the Example 4, First step and 7-azaindole-3-carboxaldehyde (0.034 g, 0.23 mmol) in ethanol (6.0 mL), L-proline (0.0030 g, 0.023 mmol) was added at ambient temperature. The mixture was refluxed for 16 h. Cooled to ambient temperature, the precipitate was collected by filtration, washed with ethanol then dried to afford the titled compound as solid (0.045 g, y. 45%).
