5-氟-6-甲氧基-1,3-二嗪烷-2,4-二酮

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 0.25 g of 5-fluoro-6-methoxy-5,6-dihydrouracil obtained in Example 1B above was placed in a reflux flask and then 1 ml of concentrated HCl was added to the flask. The flask contents were brought to refluxing temperature, and the precipitation of a solid soon occurred, producing 0.1 g of 5-fluorouracil. to refluxing temperature the precipitation of a solid
