Participants

Reaction Steps

To a solution of 1.06 g (8 mmol) 5-hydroxyindole and 2.09 g (8 mmol) triphenylphosphine in 40 ml anhydrous THF, cooled to 0° C. in ice, was added 1.0 mL (8 mmol) 4-fluorophenethylalcohol and 1.6 ml (8 mmol) diisopropylazodicarboxylate. The solution was allowed to gradually come to room temperature overnight. The solution was concentrated and the residue was chromatographed on silica using 20-25% EtOAc-hexane to afford 0.525 g 5-[2-(4-fluoro-phenyl)-ethoxy]-1H-indole as a white solid.
