実験手順

In 20.8 ml of pyridine were dissolved 5.2 g (40 m mol) of 5-fluorouracil and 9.8 g (140 m mol) of 2,3-dihydrofuran. The solution was heated at about 160° C. in a closed tubular reactor under agitation for 5 hours. The resultant reaction mixture was treated similarly to Example 7 to give the above mentioned-compound.
