Substantially the same procedure as in Example 7 was repeated using 2.5 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 2.9 g (13.9 mmol) of 4-methoxy-2,5-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.43 g (yield 52%) of Compound 74 as white crystals.
