Procedure
Substantially the same procedure as in Reference Example 1 was repeated using 5.90 g (26.0 mmol) of 5,6-diamino-1,3-dipropyluracil and 5.5 g (31.3 mmol) of 3,4-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 7.70 g (yield of Compound 30 as a white powder.
