Procedure

A reaction vessel was charged with 0.5 g of 1-benzyloxy-3,5-dichloro-4-(3-(5-trifluoromethylpyridin-2-yloxy)propyloxy)benzene and 50 ml of ethyl acetate, and the air in the vessel was replaced with nitrogen. Then, 0.3 g of 10% palladium carbon was added, and the nitrogen in the vessel was replaced with hydrogen, followed by stirring at room temperature for 24 hours. The hydrogen in the vessel was replaced with nitrogen, after which the reaction mixture was filtered through Celite, and the filtrate was concentrated, which afforded 0.36 g of 3,5-dichloro-4-(3-(5-trifluoromethylpyridin-2-yloxy)-propyloxy)phenol (92% yield).
