Substantially the same procedure as in Reference Example 1 was repeated using 4.25 g (18.8 mmol) of 5,6-diamino-1,3-dipropyluracil and 4.33 g (22.6 mmol) of 3,4-methylenedioxycinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane to give 4.92 g (yield 69%) of Compound 18 as a pale yellow powder.
