Procedure
39 g (107.6 mmol) of tert-butyl-{3,3,3-trifluoro-2-[(2-hydroxy-1-phenylethyl)amino]-2-methylpropyl}carbamate from Example 50A were initially charged under argon in ethanol (700 ml), and 5.44 g (53.8 mmol) of palladium(II) hydroxide (20% on activated carbon, water-moist, about 60%) were added. The reaction mixture was hydrogenated at standard pressure for 16 h. Then the reaction mixture was filtered through silica gel and concentrated. The residue was purified by means of silica gel chromatography (cyclohexane/ethyl acetate gradient: 9/1 to 6/4). This gave 15.8 g (61% of theory) of the target compound.
