Substantially the same procedure as in Reference Example 1 was repeated using 1.25 g (5.52 mmol) of 5,6-diamino-1,3-dipropyluracil and 1.35 g (6.08 mmol) of 2,4-dimethoxy-3-methylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 1.14 g (yield 50%) of Compound 14 as white needles.
