Procedure
31.3 g (0.106 mol) of 4-(2-hydroxy-1,1,1-trifluoro-2-propyl)phenol benzyl ether were hydrogenated in 380 ml of glacial acetic acid in the presence of 6.3 g of palladium (5% on charcoal) at 50° C. After filtration to remove the catalyst and concentration, 18.9 g (87% of theory) remained of a colorless product.
