5,6-Diamino-1,3-diethyluracil → 1H-Purine-2,6-dione, 3,7-dihydro-1,3-diethyl-8-(2-(2,5-dimethyl-4-methoxy)phenyl)ethenyl)-, (E)-

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 2.9 g (13.9 mmol) of 4-methoxy-2,5-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 2.43 g (yield 52% ) of Compound 74 as white crystals.
