Reaction Steps

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 2.48 g (13.9 mmol) of 3-methoxycinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide/water to give 2.10 g (yield 49%) of Compound 102 as a white powder.
