実験手順

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.017 g, 0.049 mmol) obtained in Example A16, Step 1 in methanol (2.0 mL) was added with 6-ethynyl-1H-pyrrolo[2,3-b]pyridine-3-carboxaldehyde (0.007 g, 0.041 mmol). Then, the mixture was added with 5 drops of piperidine, and then the mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure, and then the residue was washed with methylene chloride to obtain tert-butyl (Z)-4-({2-[(6-ethynyl-1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.015 g, 60%).
