To 491 mg (2.00 mmol) 4-hydroxy-1-[2-(4-hydroxymethyl-phenyl)-ethyl]-1H-pyridin-2-one (preparation 2b) in 20 mL DMF is added 0.35 g (2.00 mmol) methanesulfonic acid furan-2-ylmethyl ester and 0.83 g (6.00 mmol) potassium carbonate. The reaction mixture is stirred overnight at RT, filtered and is directly transferred to a reverse HPLC for purification (Zorbax stable bond C18; water (0.15% formic acid)/acetonitrile 95:5 to 10:90).
