To 1.00 g (4.97 mmol) 4-benzyloxy-1H-pyridin-2-one in THF at 0° C. is added subsequently 613 mg (5.47 mmol) potassium-tert-butylate, 92 mg (0.25 mmol) tetra-butylammonium-iodide and 2.38 g (7.46 mmol) 1-[7-(2-chloro-acetyl)-1,2,4,5-tetrahydro-3-benzazepin-3-yl]-2,2,2-trifluoro-ethanone. The reaction mixture is stirred overnight at RT and the solvent is evaporated. The residue is taken up in DCM and aqueous 2M sodium hydroxide solution. The layers are separated, the organic phase is washed with water, dried over MgSO4, filtered and the solvent is evaporated. The residue is purified via chromatography (silica gel; DCM/MeOH 95:5) and then via reverse HPLC purification (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile 95:5 to 5:95).
