Методика

Substantially the same procedure as in Example 7 was repeated using 2.0 g (10.1 mmol) of 5,6-diamino-1,3-diethyluracil and 2.52 g (11.1 mmol) of 3-bromocinnamic acid. Then, the resultant crude crystals were recrystallized from tetrahydrofuran/water to give 2.01 g (yield 37%) of Compound 154 as pale green plates.
