Procedure
To 1.05 g (3.42 mmol) 1-[7-(2-chloro-ethyl)-1,2,4,5-tetrahydro-3-benzazepin-3-yl]-2,2,2-trifluoro-ethanone in 5 mL DMF is added at 0° C. cesium carbonate and after 15 min 600 mg (2.74 mmol) 4-(4-fluoro-benzyloxy)-1H-pyridin-2-one (preparation 22.1). The reaction mixture is stirred overnight at RT and is then added to 50 mL 1 M aqueous NaOH-solution. The mixture is stirred 2 h at RT. The aqueous phase is extracted with tert-butylmethylether. The combined organic phase is dried over MgSO4, filtered and the solvent is evaporated. The residue is purified via reverse HPLC chromatography (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile (0.15% formic acid) 95:5 to 5:95).
