Reaction Steps

A solution of 7-[(cis-3,5-dimethylpiperazin-1-yl)methyl]-6-hydroxybenzofuran-3(2H)-one (0.166 g, 0.601 mmol) in methanol (2.4 mL) was added with 1H-indazole-3-carbaldehyde (0.0878 g, 0.601 mmol), and piperidine (0.00512 g, 0.0601 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 (8 mL), suspended in methanol, and thereby washed to obtain (Z)-2-[(1H-indazol-3-yl)methylene]-7-[(cis-3,5-dimethylpiperazin-1-yl)methyl]-6-hydroxybenzofuran-3(2H)-one (0.197 g, 81%).
