Procedure

A mixture of ethyl 2-(2′-fluoro-2,4′-bipyridin-5-yl)acetate 208-2 (93 mg, 0.36 mmol) and NaOH (57 mg, 1.43 mmol) in THF (0.5 mL) and water (0.5 mL) was stirred at 65° C. for 3 hours. After cooled down to room temperature, the mixture was treated with 3N HCl aqueous solution to adjust the pH around 3, and then stirred for 15 minutes. The resulting solution was evaporated to dryness and the remaining solid was extracted with 20% methanol in ethyl acetate. The organic portion was concentrated to give 2-(2′-fluoro-2,4′-bipyridin-5-yl)acetic acid 208-3 as pale white solid. MS m/z 233.1 (M+1).
