Reaction Steps

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 2.68 g (13.9 mmol) of 3-nitrocinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.01 g (yield 30%) of Compound 152 as a yellow powder.
