Reaction Steps

Substantially the same procedure as in Reference Example 70 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 2.50 g (13.9 mmol) of 3-fluoro-2-methylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane to give 2.18 g (yield 51%) of Compound 180 as a white powder.
