Substantially the same procedure as in Example 7 was repeated using 1.0 g (5.88 mmol) of 5,6-diamino-1,3-dimethyluracil and 1.35 g (6.48 mmol) of 2,4-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide to give 221 mg (yield 11%) of Compound 90 as pale yellow grains.
