Participants

Reaction Steps

Substantially the same procedure as in Reference Example 70 was repeated using 2.5 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 2.48 g (13.9 mmol) of 2-methoxycinnamic acid. Then, the resultant crude crystals were recrystallized from tetrahydrofuran/water to give 990 mg (yield 24%) of Compound 157 as yellow grains.
