Reaction Steps

To 100 mg (0.21 mmol) 4-benzyloxy-1-{2-hydroxy-2-[3-(2,2,2-trifluoro-acetyl)-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl]-ethyl}-1H-pyridin-2-one (example 22.2) in 5.0 mL MeOH is added 0.41 mL (0.41 mmol) aqueous 1 M sodium hydroxide solution. The reaction mixture is stirred 2 h at RT. The solvent is evaporated, the residue is dissolved in DMF and purified via reverse HPLC chromatography (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile 95:5 to 5:95).
