実験手順
To a solution of (1-methyl-1H-benzimidazol-2-yl)methanol (1.1 g, 6.8 mmol) in anhydrous dichloromethane (60 mL) was added dropwise phosphorus tribromide (1.3 mL, 14.0 mmol). The mixture was stirred at room temperature overnight. Dichloromethane was evaporated. The residue was dried in vacuo, affording 2-(bromomethyl)-1-methyl-1H-benzimidazole hydrobromide. The product was used without further purification.
