Versuchsvorschrift

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 2.70 g (16.7 mmol) of 4-methylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane to give 2.64 g (yield 54%) of Compound 106 as pale yellow needles.
