Substantially the same procedure as in Reference Example 1 was repeated using 2.5 g (11.1 mmol) of 5,6-diamino-1,3-dipropyluracil and 2.51 g (12.17 mmol) of 4-methoxy-2,5-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from ethanol/water to give 1.98 g (yield 45%) of Compound 44 as white crystals.
