실험 절차

Concentrated hydrochloric acid (0.7 ml) was added to a mixture of the crude N-benzhydrylidene-N′-(7-fluoro-2-methyl-1H-benzimidazol-5-yl)-hydrazine (325 mg) and ethanol (0.7 ml). This was stirred at 59 to 64° C. for one hour, and the reaction mixture was cooled to room temperature. Then, the precipitated solid was collected by filtration and dried. Thus, 7-fluoro-2-methyl-1H-benzimidazol-5-yl-hydrazine dihydrochloride (90 mg, 80%) was obtained.
