실험 절차

1-Bromobutane (3.75 g, 27.33 mmol) and potassium carbonate (10.3 g, 74.52 mmol) were added to a solution of 4-benzyloxy-1H-pyridin-2-one (5.0 g, 24.84 mmol) in acetonitrile (200 ml) and the mixture was heated at reflux temperature for 16 hours. Subsequently, the reaction mixture was filtered through diatomaceous earth and concentrated in vacuo. The crude residue was then triturated with diethyl ether to yield pure D4 (6.26 g, 98%) as a white solid.
