Versuchsvorschrift

The reaction of 3-(N,N-dipropylcarbamoyl)propionic acid and diphenylphosphoryl azide in a solution of triethylamine and benzene provided a solution comprising 2-(N',N'-dipropylcarbamoyl)ethyl isocyanate (I.R.: 2280 cm-1), which was reacted with 5-fluorouracil to provide 1-[N-[2-(N',N'-dipropylcarbamoyl)ethyl]carbamoyl]-5-fluorouracil substantially in the similar method to that of Example 4.
