Versuchsvorschrift

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.026 g, 0.075 mmol) obtained in Example A16, Step 1 in methanol (2.0 mL) was added with 6-phenyl-1H-pyrrolo[2,3-b]pyridine-3-carboxaldehyde (0.013 g, 0.059 mmol). Then, the mixture was added with 5 drops of piperidine, and the mixture was stirred overnight at room temperature. 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-3-oxo-2-[(6-phenyl-1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.019 g, 46%).
