실험 절차

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.067 g, 0.19 mmol) obtained in Example A16, Step 1 in methanol (5.0 mL) was added with 5-(2-morpholinoethoxy)-1H-indole-3-carboxaldehyde (0.044 g, 0.16 mmol). Then, the mixture was added with 5 drops of piperidine, and the mixture was stirred at 50° C. for 2 hours. The solvent was evaporated under reduced pressure, and then the residue was subjected to silica gel column chromatography (eluted with chloroform/methanol (95:5)) to obtain tert-butyl (Z)-4-[(6-hydroxy-2-{[5-(2-morpholinoethoxy)-1H-indol-3-yl]methylene}-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.076 g, 81%).
