To 5.00 g (10.3 mmol) 4-benzyloxy-1-{2-oxo-2-[3-(2,2,2-trifluoro-acetyl)-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl]-ethyl}-1H-pyridin-2-one (preparation 21a) in 100 mL MeOH and 9.8 mL 1 M aqueous HCl-solution is added 500 mg of 10% Pd/C. The reaction mixture is stirred under a hydrogen atmosphere of 5000 hPa at 50° C. for 18 h. After filtration and evaporation of the solvent, is the residue purified by HPLC (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile 95:5 to 5:95).
