Acetyl-5-bromo-6-methoxynaphthalene(1) was hydrogenated over Pd/C by bubbling H₂ into a mixture of n-BuOH, KOH(aq) and CTAB. The effects of the concentration of KOH and n(1): n(Pd): n(CTAB) on the hydrogenation were investigated. Bubbling H₂ for 4.25 h at 60℃ into the mentioned mixture solution gave 6-methoxy-2-naphthylethanol in yield of 95.7%.
