Reaction Steps

Substantially the same procedure as in Reference Example 70 was repeated using 3.00 g (15.1 mmol) of 5,6-diamino-1,3-diethyluracil and 3.48 g (16.7 mmol) of 3,5-dimethoxy-cinnamic acid. Then, the resultant crude crystals were recrystallized from ethanol/water to give 2.74 g (yield 49%) of Compound 129 as a white powder.
