Reaction Steps

A solution of 6-hydroxy-7-[(4-methylpiperazin-1-yl)methyl]benzofuran-3(2H)-one (0.131 g, 0.500 mmol) in methanol (2 mL) was added with 1H-indazole-3-carbaldehyde (0.0731 g, 0.500 mmol), and piperidine (0.00426 g, 0.0500 mmol) at room temperature, and the mixture was stirred at 60° C. for 2 hours. The reaction mixture was cooled to room temperature, then added with methanol (2 mL), and suspended in methanol and thereby washed to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-6-hydroxy-7-[(4-methylpiperazin-1-yl)methyl]benzofuran-3(2H)-one (0.0731 g, 37%).
