Then, 4.4 g of 4-(4-ethoxyphenoxy)-2-isopropylphenyl benzyl ether and 100 ml of ethyl acetate were charged into a reaction vessel, and air in the vessel was replaced with nitrogen. Then, 0.50 g of 5% palladium-carbon was added, and nitrogen in the vessel was replaced with hydrogen, followed by vigorous stirring at room temperature for 24 hours. After hydrogen in the vessel was replaced with nitrogen, the reaction vessel was filtered with Celite, and the flitrate was concentrated. The residue was subjected to silica gel chromatography to give 3.1 g of 2-isopropyl-4-(4-ethoxyphenoxy)phenol (yield, 93%).
