Procedure

In 50 ml of absolute ethyl alcohol was dissolved 4.0 g of 1-(3-diethylaminopropyl)-3-amino-5-hydroxyindazole, and into the solution was introduced dried hydrogen chloride gas under cooling with ice. To the solution was added anhydrous diethyl ether to separate crystals. Then the crystals were obtained by filtration and dried to give 1-(3-diethylaminopropyl)- 3-amino-5-hydroxyindazole dihydrochloride having the following analytical value.
