実験手順
Methyl 2-(4-fluorophenyl)isonicotinate (278 mg, 1.20 mmol) was dissolved in methanol (2 mL) and the solution was added with 2 mol/L aqueous sodium hydroxide solution (2 mL, 4.0 mmol), followed by stirring at room temperature overnight. The solvent was evaporated under reduced pressure and the obtained reaction mixture was dissolved in water. The solution was washed with ethyl acetate, then was added with 1 mol/L hydrochloric acid, and the obtained crystal was collected by filtration to obtain 2-(4-fluorophenyl)isonicotinic acid (134 mg, 51%).
