Reaction Steps
2-(4-Fluorophenyl)-3-(pyridin-4-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine dihydrochloride (183 mg) was dissolved in hot aqueous isopropyl alcohol solution 15.5 ml). The solution was cooled and the separated solid was collected, washed with isopropyl alcohol and dried to give 2-(4-fluorophenyl)-3-(pyridin-4-yl)-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine hydrochloride 182 mg).
