Reaction Steps

In 50 ml of absolute ethyl alcohol was dissolved 4.0 g of 3-(2-piperidinoethylamino)indazole and into the solution was introduced dried hydrogen chloride gas under cooling with ice. Anhydrous diethyl ether was added to the solution to separate crystals. Then the crystals were obtained by filtration and dried to give 3-(2-piperidinoethylamino)indazole hydrochloride.
