실험 절차

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.020 g, 0.058 mmol) obtained in Example A16, Step 1 in methanol (2.0 mL) was added with 6-methyl-1H-pyrrolo[2,3-b]pyridine-3-carboxaldehyde (0.010 g, 0.063 mmol). Then, the mixture was added with 5 drops of piperidine, and then the mixture was stirred at 50° C. for 2 hours. The solid formed was collected by filtration, and washed with methanol to obtain tert-butyl (Z)-4-({6-hydroxy-2-[(6-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.023 g, 81%).
