Substantially the same procedure as in Reference Example 70 was repeated using 3.00 g (15.1 mmol) of 5,6-diamino-1,3-diethyluracil and 3.06 g (16.6 mmol) of 3,5-difluorocinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 3.30 g (yield 63% of Compound 155 as pale yellow plates.
