Procedure

Lithium hydroxide monohydrate (42 mg) was added to the above-obtained 1-(6-methoxy-3-pyridyl)-5-(3-pyridazinyl)pyrazole-3-carboxylic acid methyl ester (309 mg) in methanol (20 mL), and the resultant mixture was refluxed under heat for 18 hours, and then cooled in air. The reaction solvent was removed under reduced pressure, to thereby give the title compound as an amorphous product (322 mg, >100%).
