5 N Aqueous sodium hydroxide solution (2 mL) and methanol (4 mL) were added to acetic acid 4-methyl-pyridin-2-ylmethyl ester (774 mg, 4.69 mmol) described in Manufacturing Example 11-1-2, and this mixture was stirred for 10 minutes at 60° C. The reaction solution was partitioned into water and ethyl acetate. The separated aqueous layer was further extracted with ethyl acetate twice. The ethyl acetate layers were combined and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure to obtain the title compound (410 mg, 71.0%).
