실험 절차

A solution of tert-butyl (E)-4-[3-(6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl)allyl]piperidine-1-carboxylate (0.0313 g, 0.0807 mmol) in methanol (3 mL) was added with 1H-indazole-3-carboxaldehyde (0.0118 g, 0.0807 mmol) and piperidine (0.0800 mL, 0.810 mmol), and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was concentrated, and the resulting residue was purified by silica gel column chromatography (chloroform/methanol) to obtain tert-butyl 4-((E)-3-{(Z)-2-[(1H-indazol-3-yl)methylene]-6-methoxy-3-oxo-2,3-dihydrobenzofuran-7-yl}allyl)piperidine-1-carboxylate (0.0308 g, 74%).
