Reaction Steps
4-(6-Benzyloxy-2-naphthyloxy)benzoic acid ethyl ester (10.6 g, 26.2 mmol) was dissolved in a 2:1 mixture of THF and methanol (150 ml), added with 4N lithium hydroxide (33 ml) and stirred at room temperature. After completing the reaction, the reaction liquid was adjusted to pH 2 or thereabout with 1N hydrochloric acid, extracted with ethyl acetate, washed with water, dried with magnesium sulfate and concentrated to obtain the subject compound (8.70 g, 23.4 mmol). The result of 1H-NMR was consistent with the above structure.
