To 1.23 g (5.00 mmol) 4-hydroxy-1-[2-(4-hydroxymethyl-phenyl)-ethyl]-1H-pyridin-2-one (preparation 2b) in 8.0 mL DMF is added 1.26 g (5.00 mmol) 5-bromo-2-bromomethyl-pyridine and 2.07 g (15.0 mmol) potassium carbonate. The reaction mixture is stirred overnight at RT, diluted with 80 mL of water, the formed precipitate is collected and dissolved in DMF. The solution is directly transferred to a reverse HPLC for purification (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile 95:5 to 10:90).
