Reaction Steps

A solution of tert-butyl 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazine-1-carboxylate (0.100 g, 0.287 mmol) obtained in Example A16, Step 1 in methanol (1 mL) was added with 7-aza-1H-indole-3-carboxaldehyde (0.0502 g, 0.344 mmol) and piperidine (0.00244 g, 0.0287 mmol), and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was cooled to room temperature, and then the precipitated solid was collected by filtration to obtain tert-butyl (Z)-4-({2-[(1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazine-1-carboxylate (0.0798 g, 58%).
