Substantially the same procedure as in Reference Example 1 was repeated using 3.00 g (13.3 mmol) of 5,6-diamino-1,3-dipropyluracil and 2.67 g (14.6 mmol) of 2-chlorocinnamic acid. Then, the resultant crude crystals were recrystallized from toluene to give 3.72 g (yield 82%) of Compound 40 as white needles.
