Versuchsvorschrift

Substantially the same procedure as in Reference Example 1 was repeated using 2.31 g (10.24 mmol) of 5,6-diamino-1,3-dipropyluracil and 2.42 g (15.4 mmol) of 4-methoxy-2,3-dimethylcinnamic acid. Then, the resultant crude crystals were recrystallized from dioxane/water to give 1.96 g (yield 48%) of Compound 12 as a white powder.
