Versuchsvorschrift

Substantially the same procedure as in Example 7 was repeated using 2.50 g (14.7 mmol) of 5,6-diamino-1,3-dimethyluracil and 3.37 g (16.2 mmol) of 2,3-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from ethanol/water to give 1.03 g (yield 41%) of Compound 88 as pale yellow needles.
