Reaction Steps

To 500 mg (1.62 mmol) 1-[2-(4-bromomethyl-phenyl)-ethyl]-4-hydroxy-1H-pyridin-2-one (preparation 4) in 2.5 mL DMF is added at RT 482 mg (1.79) piperidine-4-carboxylic acid dimethylamide and 0.46 mL (3.25 mmol) triethylamine. The mixture is stirred overnight at RT and after filtration is purified via HPLC chromatography (Zorbax stable bond, C18; water (0.15% formic acid)/acetonitrile 95:5 to 5:95).
