Reaction Steps

To 200 mg (0.53 mmol) 4-hydroxy-1-{2-[3-(2,2,2-trifluoro-acetyl)-2,3,4,5-tetrahydro-1H-3-benzazepin-7-yl]-ethyl}-1H-pyridin-2-one (preparation 21b) in DMF is added 145 mg (1.05 mmol) potassium carbonate and the mixture is stirred 10 min at RT before 133 mg (0.53 mmol) 2-(bromomethyl)-pyridine hydro-bromide is added. The reaction mixture is stirred 5 h at RT and is directly purified via reverse HPLC chromatography (Zorbax stable bond, C18; water (0.1% formic acid)/acetonitrile (0.1% formic acid) 95:5 to 5:95).
