Reaction Steps

A solution of 5-chloro-7-[(4-methylpiperazin-1-yl)methyl]benzofuran-3(2H)-one (0.12 g, 0.43 mmol) in methanol (5.0 mL) was added with 1H-indazole-3-carboxaldehyde (0.063 g, 0.43 mmol). Then, the mixture was added with 7 drops of piperidine, and then the mixture was stirred at 60° C. for 2 hours. The reaction mixture was concentrated, and then the residue was purified by silica gel column chromatography (eluted with chloroform/methanol (99:1→90:10)) to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-5-chloro-7-[(4-methylpiperazin-1-yl)methyl]benzofuran-3(2H)-one (0.042 g, 24%).
