N-Iodosuccinimide → 5-Benzyl-4-iodo-2-(4-isopropyl-phenyl)-7-methoxy-1-(2-methoxy-ethyl)-1H-benzoimidazole

Participants

Reaction Steps

417 mg (1.78 mmol) N-iodo-succinimide are added to a solution of 670 mg (1.62 mmol) 5-benzyl-2-(4-isopropyl-phenyl)-7-methoxy-1-(2-methoxy-ethyl)-1H-benzoimidazole in 25 ml acetonitrile. The reaction mixture is stirred at reflux temperature for 3 h. The reaction mixture is poured on water and extracted (3×) with ethyl acetate. The combined organic layers are washed with water and brine, dried over MgSO4, filtered and concentrated in vacuo. The residue is purified by flash-chromatography on silica gel (hexane:EtOAc=4:1) to afford 582 mg of the title compound as a white crystalline solid.
