A solution of 3-(2-phenylpyrazolo[1,5-a]pyridin-3-yl)-2-hydroxyiminopropionic acid (0.20 g) in acetic anhydride (1 ml) was stirred for an hour at 80° C. After cooling, to the mixture was added water (10 ml). The resulting precipitates were collected by filtration to give 2-(2-phenylpyrazolo[1,5-a]pyridin-3-yl)acetonitrile (0.10 g).
