実験手順

Thionyl chloride ((10 ml) was added to a suspension of 5-(hydroxymethyl)-2,4(1H,3H)-pyrimidinedione (0.60 g, 4.2 mmol)from step (11a) in dioxane (15 ml). The reaction was heated to reflux for 4 h, allowed to cool, and concentrated in vacuo to give the 5-(chloromethyl)-2,4(1H,3H)-pyrimidinedione (0.62 g, 100%) as a yellow solid.
