実験手順

Substantially the same procedure as in Example 7 was repeated using 2.50 g (12.6 mmol) of 5,6-diamino-1,3-diethyluracil and 3.31 g (14.9 mmol) of 3-methoxy-4,5-methylenedioxycinnamic acid. Then, the resultant crude crystals were recrystallized from tetrahydrofuran/water to give 600 mg (yield 53%) of Compound 169 as a white powder.
