실험 절차

Excess 3% hydrogen chloride in methanol is added to a solution of 1.0 g. 2-(1,4-benzodioxan-2-ylmethyl)-benzimidazole in 20 ml methanol. Diethyl ether is added until precipitation is complete. The product is filtered, washed with ether, air dried and recrystallized from methanol/acetone to yield 2-(1,4-benzodioxan-2-ylmethyl)benzimidazole hydrochloride, m.p. 221°-224° C.(d).
