Versuchsvorschrift

To 50 mg (0.13 mmol) 1-{4-[2-(4-hydroxy-2-oxo-2H-pyridin-1-yl)-ethyl]-benzyl}-piperidine-4-carboxylic acid dimethylamide (example 17.1a) in 2.0 mL DMF is added 130 μL (1 M solution in 1,4-dioxane, 0.13 mmol) 2-bromomethyl-thiophene and 45 mg (0.33 mmol) potassium carbonate at 0° C. The reaction mixture is stirred overnight at RT, filtered and the solvent is evaporated. The residue is dissolved in 2.5 mL of DMF and is purified via reverse HPLC chromatography (Waters symmetry, C18, 7 μm; water (0.15% formic acid)/acetonitrile 95:5 to 5:95).
