Procedure
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 3.77 g (13.9 mmol) of 2-bromo-4,5-methylenedioxycinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylsulfoxide/water to give 2.01 g (yield 38%) of Compound 165 as a yellow powder.
