Substantially the same procedure as in Example 7 was repeated using 5.00 g (29.4 mmol) of 5,6-diamino-1,3-dimethyluracil and 7.71 g (32.4 mmol) of 2,3,4-trimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from isopropanol/water to give 3.78 g (yield 35%) of Compound 82 as an ocher powder.
