Substantially the same procedure as in Reference Example 1 was repeated using 2.00 g (8.85 mmol) of 5,6-diamino-1,3-dipropyluracil and 2.32 g (9.73 mmol) of 2,3,4-trimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from 2-propanol/water to give 1.84 g (yield 49%) of Compound 21 as pale yellow needles.
