실험 절차

A reaction vessel was charged with 35 g of 4-benzyloxy-3-chloro-5-methyl-1-benzoyloxybenzene and 200 ml of ethyl acetate, and the air in the vessel was replaced with nitrogen. Then, 2 g of 10% palladium carbon was added, and the nitrogen in the vessel was replaced with hydrogen, followed by vigorous stirring at room temperature for 10 hours. The hydrogen in the vessel was replaced with nitrogen, after which the reaction mixture was filtered, and the filtrate was concentrated. The residue was subjected to silica gel chromatography, which afforded 25 g of 4-benzoyloxy-2-chloro-6-methylphenol (96% yield).
