Reaction Steps

A mixture of 0.6 g (2.6 mmol) 5-(4-trifluoromethoxy-phenyl)-1H-indole, 0.53 mL (2.8 mmol) 4-(trifluoromethoxy)iodobenzene, 0.075 g (0.52 mmol) copper(I) bromide and 0.54 g (3.9 mmol) K2CO3 in 10 mL anhydrous N-methylpyrrolidinone was heated to reflux overnight with stirring. The reaction was allowed to cool and was then poured into 200 mL of water. The aqueous solution was shaken with 200 mL ethyl acetate, the combined aqueous and organic phases were filtered, and the organic phase was separated. The aqueous phase was extracted once more with 200 mL ethyl acetate and the combined organic phases were washed with brine and concentrated. The crude product was chromatographed on silica (5–7% EtOAc-hexane as elutant) to afford 0.505 g (44% yield) of 1,5-bis-(4-trifluoromethoxy-phenyl)-1H-indole.
