Procedure

A 5 N sodium hydroxide solution (400 μL) was added to a solution of methyl 5-(2-fluoroethoxy)pyrazine-2-carboxylate obtained in Preparation Example 53-(1) (200 mg) in ethanol (4 mL). Water was added until the reaction solution became a complete solution, followed by stirring at room temperature for 10 minutes. The reaction solution was made acidic with 5 N hydrochloric acid. Saturated aqueous sodium chloride and ethyl acetate were added to the reaction solution, and the organic layer was separated. The organic layer was dried over anhydrous magnesium sulfate. The organic layer was concentrated under reduced pressure to obtain the title compound (150 mg).
