Reaction Steps
Sodium azide (350 mg, 5.38 mmol) was added to a solution of methanesulfonic acid, 2-(2-benzotriazol-1-ylmethyl-benzimidazol-1-yl)-ethyl ester (200 mg, 0.54 mmol) in 5 mL of anhydrous N,N-dimethylformamide. The reaction temperature was raised to 105° C. and stirred for 4 hours. The mixture was cooled, diluted with water and extracted with diethyl ether (3×100 mL). The combined ether extracts were dried over magnesium sulfate, filtered, and evaporated under vacuum. This gave the title compound as a white solid (160 mg, 94% yield).
