Reaction Steps
To a ethanol (21 ml) solution of 3-(3-methylpyridazin-4-yl)-2-phenylpyrazolo[1,5-a]pyridine (0.42 g) was added 20 W/V % ethanolic hydrogen chloride solution at room temperature, and stirred for an hour. The precipitates were collected by filtration to give 3-(3-methylpyridazin-4-yl)-2-phenylpyrazolo[1,5-a]pyridine hydrochloride (0.23 g).
