실험 절차

Substantially the same procedure as in Example 7 was repeated using 2.85 g (14.4 mmol) of 5,6-diamino-1,3diethyluracil and 2.70 g (13.1 mmol) of 3-(1,4-benzodioxan-6-yl)acrylic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.45 g (yield 51%) of Compound 80 as a pale yellow powder.
