Reaction Steps

A concentrated hydrochloric acid (5 ml) was added to 3-(3-methoxypyridazin-4-yl)-2-phenylpyrazolo[1,5-a]pyridine (0.50 g) and refluxed for 2 hours and 30 minutes. After cooling, to the reaction mixture was added water (10 ml). The precipitates were collected by filtration to give 3-(3-oxo-2,3-dihydropyridazin-4-yl)-2-phenylpyrazolo[1,5-a]pyridine (0.41 g).
