실험 절차

To a suspension of 2-(4-fluorophenyl)-3-(pyridin-4-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine (100 mg) in methanol (2 ml) was added 10% methanolic hydrogen chloride (0.5 ml). The resulting clear solution was concentrated in vacuo. To the residue was added ethanol (3 ml) and the solution was concentrated in vacuo. The residue was crystallized from a mixture of ethanol and diethyl ether to give 2-(4-fluorophenyl)-3-(pyridin-4-yl)4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine dihydrochloride (100 mg).
