A mixture of 2-(2-phenylpyrazolo[1,5-a]pyridin-3-yl)acetonitrile (0.23 g), 85% sodium hydroxide (0.33 g) and 80% aqueous methanol was refluxed for 15 hours. The reaction mixture was acidified with 5% hydrochloric acid (pH ≈1) and the precipitates were collected by filtration to give 2-(2-phenylpyrazolo[1,5-a]pyridin-3-yl)acetic acid (0.23 g).
