実験手順
Substantially the same procedure as in Reference Example 70 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 2.31 g (13.9 mmol) of 4-fluorocinnamic acid. Then, the resultant crude crystals were recrystallized from tetrahydrofuran/water to give 2.00 g (yield 51%) of Compound 149 as colorless columns.
