Ethyl 8-allyl-7-hydroxynaphthalene-2-carboxylate (4 g) in ethanol was hydrogenated at 3 atmospheres in the presence of a 5% palladium charcoal catalyst for 1 hour. Filtration and evaporation of the filtrate gave a solid, which crystallised from benzene-petroleum ether (b.p. 60-80) to give ethyl 7-hydroxy-8-propylnaphthalene-2-carboxylate (3.2 g), m.p. 114°-115°.
