Substantially the same procedure as in Reference Example 1 was repeated using 3.95 g (17.5 mmol) of 5,6-diamino-1,3-dipropyluracil and 3.51 g (19.2 mmol) of 3-chlorocinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide/water to give 4.44 g (yield 67%) of Compound 38 as pale yellow crystals.
