Procedure

To 400 mg (1.63 mmol) 4-hydroxy-1-[2-(4-hydroxymethyl-phenyl)-ethyl]-1H-pyridin-2-one (preparation 2b) in 20 mL DMF is added 0.45 g (1.79 mmol) 4-bromomethyl-pyridine and 0.68 g (4.89 mmol) potassium carbonate. The reaction mixture is stirred overnight at RT, diluted with 60 mL of EtOAc and is washed twice with water. The organic phase is dried over MgSO4, filtered and the solvent is evaporated. The residue is purified via reverse HPLC chromatography (Waters symmetry C18; water (0.15% formic acid)/acetonitrile 95:5 to 10:90).
