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 2.3 g (13.9 mmol) of 2,3,4-trimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.85 g (yield 57% of Compound 70 as white crystals.
