Reaction Steps

To a mixture of 0.58 g (3 mmol) of 3-acetyl-5-chloroindole, 1.42 g (5.4 mmol) of triphenylphosphine and 0.66 g (5.4 mmol) of phenethyl alcohol in THF (12 ml) was added under ice-cooling, 1.09 g (5.4 mmol) of diisopropyl azodicarboxylate. After stirring for 3 hours at room temperature, the mixture was concentrated under reduced pressure. The obtained residue was chromatographed on silica gel (¼ ethyl acetate/toluene as eluant) to give 0.58 g of the titled compound as an oil. Yield: 65%.
