Reaction Steps

A mixture of 50 mg (0.111 mmol) 4-iodo-2-(4-isopropyl-phenyl)-7-methoxy-1-(2-methoxy-ethyl)-1H-benzoimidazole, 0.1 ml (0.77 mmol) triethylamine, 0.1 ml (0.7 mmol) ethinyltrimethylsilane and 5 mg palladium-II-acetate in 1 ml acetonitrile is stirred at 50° C. for 3 hours. Then the reaction mixture is cooled to room temperature and 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=3:1) to afford 17 mg of the title compound as colorless oil.
