実験手順

To 3.29 g (16.4 mmol) 4-benzyloxy-1H-pyridin-2-one in 16 mL DMF is added 13.3 g (40.9 mmol) cesium carbonate and the mixture is stirred 15 min at RT. Then 3.75 g (16.4 mmol) 2-bromo-1-(4-hydroxymethyl-phenyl)-ethanone (preparation 15a) is added and is stirred 2 h at RT. Water is added, the precipitate is collected, washed with water and dried.
