Reaction Steps
To a mixture of 5-hydroxy-1-naphthyl trifluoromethane-sulfonate (8.0 g) in N,N-dimethylformamide (35 ml) and ethanol (5.0 ml) were added 1,3-bis(diphenylphosphino)-propane (621 mg), palladium acetate(II) (3.7 mg) and triethylamine (1.35 g), and the mixture was stirred at 100° C. for 1 hour under carbon-monoxide. The mixture was diluted with ethyl acetate and water. The organic layer was separated, washed with brine, dried over magnesium sulfate and evaporated. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=5/1) to give ethyl 5-hydroxy-1-naphthoate (1.7 g) as a colorless oil.
