3-(2,4-Dimethoxyphenyl)prop-2-enoic acid → 1H-Purine-2,6-dione, 3,7-dihydro-8-(2-(2,4-dimethoxyphenyl)ethenyl)-1,3-dipropyl-, (E)-

Participants

Reaction Steps

Substantially the same procedure as in Reference Example 1 was repeated using 3.0 g (13.3 mmol) of 5,6-diamino-1,3-dipropyluracil and 3.04 g (14.60 mmol) of 2,4-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 1.26 g (yield 24%) of Compound 25 as white crystals.
