Reaction Steps

In 15 ml of absolute ethyl alcohol was dissolved 1.50 g of 1-(3-diethylaminopropyl)-3-amino-4-chloroindazole 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-4-chloroindazole dihydrochloride having the following analytical value.
