Versuchsvorschrift

A solution of isopropyl 2-isopropoxy-4-oxo-4,5-dihydrofuran-3-carboxylate (0.10 g, 0.44 mmol) which similarly prepared according to the procedure described in the Example 74, Third step using diisopropyl malonate and chloroacetyl chloride, and cyclohexylamine (0.055 mL, 0.48 mmol) in 2-propanol (2.0 mL) was stirred at ambient temperature for 14 h. To this reaction mixture, 7-azaindole-3-carboxaldehyde (0.065 g, 0.44 mmol) and piperidine (0.0044 mL, 0.044 mmol) were added then the mixture was refluxed for further 8 days. Cooled to ambient temperature, the reaction mixture was purified by preparative HPLC to afford the titled compound as solid (0.0079 g, y. 4%).
