Reaction Conditions

Reaction Steps

To a solution of sodium azide (176 mg, 2.70 mmol) in N,N′-dimethylformamide (5 mL) was added 2-{[1-(cyclopropylmethyl)-2-(2,2-dimethylpropyl)-1H-benzimidazol-5-yl]sulfonyl}-2-methylpropyl methanesulfonate (Step I, 411 mg, 0.90 mmol) in N,N′-dimethylformamide (3 mL) at room temperature. The mixture was stirred at 160° C. for 24 h. The mixture was washed with ethyl acetate (20 mL×3) and water (30 mL). The combined organic layer was dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane:ethyl acetate=5:2 as eluent) to afford the title compound (265 mg) as a white amorphous.
