Procedure

150 mg of 4-methoxy-3-[(E)-2-(pyridin-4-yl)-vinyl]-1H-indazole-5-carboxylic acid ethyl ester was dissolved in a mixed solvent of 3 mL tetrahydrofuran/1 mL methanol, added with 0.5 mL of 5N sodium hydroxide aqueous solution, and heated at 50° C. for 4 hours. The reaction solution was neutralized with acetic acid, and the solvent distilled off under reduced pressure, to give 500 mg of the crudely produced title compound as a mixture with sodium acetate.
