Reaction Steps

1-[1-(2-Hydroxylethyl)-1-H-benzimidazol-2-ylmethyl)-1H-benzotriazole (300 mg, 1.02 mmol) was suspended in anhydrous methylene chloride and cooled to 0° C. with an ice bath. Diisopropylethylamine (0.36 ml, 2.05 mmol) and methanesulfonyl chloride (0.16 mL, 2.05 mmol) were slowly added. The reaction was stirred at 0° C. for 1 hour during which the solution became clear. The solvent was stripped under vacuum, and the residue was purified by flash chromatography (EtOAc) to give 221 mg (58%) of the title compound as a white solid.
