A solution of 6-hydroxy-7-[(4-methylpiperazin-1-yl)methyl]benzofuran-3(2H)-one (0.525 g, 2.00 mol) in methanol (10 mL) was added with 1-tosyl-1H-indole-3-carboxaldehyde (0.599 g, 2.00 mmol) and piperidine (0.017 g, 0.200 mmol), and the mixture was stirred overnight at room temperature. The reaction mixture was added with methanol, and the solid was suspended in methanol and thereby washed to obtain the objective (Z)-6-hydroxy-7-[(4-methylpiperazin-1-yl)methyl]-2-[(1-tosyl-1H-indol-3-yl)methylene]benzofuran-3(2H)-one (0.887 g, 81%).
