Substantially the same procedure as in Example 7 was repeated using 3.00 g (15.1 mmol) of 5,6-diamino-1,3-diethyluracil and 4.78 g (17.2 mmol) of 2-bromo-4,5-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane to give 3.34 g (yield 49%) of Compound 122 as pale yellow needles.
