Reaction Steps

A solution of 4-[(6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl)methyl]piperazin-2-one (0.0986 g, 0.376 mmol) in isopropanol (1.5 mL) was added with 7-aza-1H-indole-3-carboxaldehyde (0.0550 g, 0.376 mmol) and piperidine (0.00320 g, 0.0376 mmol), and the mixture was refluxed by heating for 2 hours. The reaction mixture was cooled to room temperature, and then added with isopropanol (2 mL), and the precipitated solid was suspended in isopropanol and thereby washed. The solid was collected by filtration to obtain the objective (Z)-4-({2-[(1H-pyrrolo[2,3-b]pyridin-3-yl)methylene]-6-hydroxy-3-oxo-2,3-dihydrobenzofuran-7-yl}methyl)piperazin-2-one (0.106 g, 72%).
