Product 1

HCID 64488781H-Purine-2,6-dione, 3,7-dihydro-1,3-diethyl-8-(2-(3-methoxyphenyl)ethenyl)-, (E)-Yield 49%

Procedure

Substantially the same procedure as in Example 7 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 2.48 g (13.9 mmol) of 3-methoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide/water to give 2.10 g (yield 49%) of Compound 102 as a white powder.

Workup

  1. customThen, the resultant crude crystals were recrystallized from dimethylformamide/water
