Substantially the same procedure as in Example 7 was repeated using 5.0 g (29.4 mmol) of 5,6-diamino-1,3 -dimethyluracil and 6.78 g (35.3 mmol) of 3,4-methylenedioxycinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide/water to give 1.20 g (yield 13%) of Compound 86 as a pale yellow powder.
