Reaktionsschritte
Substantially the same procedure as in Reference Example 70 was repeated using 1.0 g (5.88 mmol) of 5,6-diamino-1,3-dimethyluracil and 1.33 g (6.45 mmol) of 4-methoxy-2,5-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide to give 393 mg (yield 20%) of Compound 101 as pale yellow grains.
