Reaction Steps
A solution of tert-butyl 4-{[6-(benzyloxy)-3-oxo-2,3-dihydrobenzofuran-7-yl]methyl}piperazine-1-carboxylate (0.198 g, 0.452 mmol) in methanol (1.8 mL) was added with indole-3-carboxaldehyde (0.0656 g, 0.452 mmol) and piperidine (0.0308 g, 0.362 mmol), and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was cooled to room temperature, and then the precipitated yellow solid was collected by filtration to obtain tert-butyl (Z)-4-({2-[(1H-indol-3-yl)methylene]-6-(benzyloxy)-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.141 g, 55%).
