Reaction Steps

A mixture of 8-benzyloxy-4-ethoxycarbonyl-2-methylquinoline (663 mg) and palladium(II) hydroxide (60 mg) in a mixture of ethanol (6 ml) and dioxane (6 ml) was stirred for 3 hours at ambient temperature under hydrogen atmosphere. The reaction mixture was filtered, and the filtrate was concentrated. The residue was pulverized with n-hexane to give 4-ethoxycarbonyl-8-hydroxy-2-methylquinoline (370 mg) as pale yellow solid.
