Versuchsvorschrift

Substantially the same procedure as in Reference Example 1 was repeated using 1.35 g (5.96 mmol) of 5,6-diamino-1,3-dipropyluracil and 1.35 g (6.55 mmol) of 3-(1,4-benzodioxan-6-yl)acrylic acid. Then, the resultant crude crystals were recrystallized from ethanol/water to give 1.54 g (yield 65%) of Compound 16 as white needles.
