Procedure
Substantially the same procedure as in Example 7 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 3.0 g (13.9 mmol) of 3-trifluoromethylcinnamic acid. Then, the resultant crude crystals were recrystallized from acetonitrile/water to give 2.07 g (yield of Compound 156 as white needles.
