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-2,3-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from ethanol/water to give 0.80 g (yield of Compound 72 as white crystals.
