One part by weight of 1,4-dimorpholino-7-phenylpyrido[3,4-d]pyridazine is dissolved in 50 parts by volume of ethanol under warming. Ten parts by volume of a 10% hydrogen chloride ethanolic solution is added to the solution and the resulting mixture is cooled to precipitate 1,4-dimorpholino-7-phenylpyrido[3,4-d]pyridazine hydrochloride. The product (one part by weight) is collected by filtration and recrystallized from 50 parts by volume of ethanol to obtain highly purities 1,4-dimorpholino-7-phenylpyrido[3,4-d]pyridazine hydrochloride melting at 176 to 181°C as orange needles.
