実験手順
Substantially the same procedure as in Reference Example 1 was repeated using 2.9 g (13.1 mmol) of 1,3-diallyl-5,6-diaminouracil and 2.99 g (14.4 mmol) of 3,4-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.80 g (yield of Compound 69 as pale yellow flocculent precipitates.
