2-Chloro-3,4-dimethoxycinnamic acid → 1H-Purine-2,6-dione, 3,7-dihydro-8-(2-(2-chloro-3,4-dimethoxyphenyl)ethenyl)-1,3-diethyl-, (E)-

Participants

Reaction Steps

Substantially the same procedure as in Example 7 was repeated using 2.00 g (10.1 mmol) of 5,6-diamino-1,3-diethyluracil and 2.94 g (12.1 mmol) of 2-chloro-3,4-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from 2-propanol/water to give 2.19 g (yield 54%) of Compound 112 as pale yellow needles.
