실험 절차

Substantially the same procedure as in Reference Example 1 was repeated using 2.0 g (8.85 mmol) of 5,6-diamino-1,3-dipropyluracil and 2.2 g (10.6 mmol) of 2,3-dimethoxycinnamic acid. Then, the resultant crude crystals were recrystallized from chloroform/cyclohexane to give 1.26 g (yield 36%) of Compound 29 as yellow crystals.
