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 2.77 g (16.7 retool) of 3-fluorocinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 1.96 g (yield 40% of Compound 127 as a pale yellow powder.
