実験手順

Substantially the same procedure as in Example 7 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3 -diethyluracil and 2.79 g (15.2 mmol) of 3,4-difluorocinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.12 g (yield 49%) of Compound 116 as gray plates.
