Participants

Reaction Steps

Substantially the same procedure as in Reference Example 1 was repeated using. 3.95 g (17.5 mmol) of 5,6-diamino-1,3-dipropyluracil and 3.19 g (19.2 mmol) of 3-fluorocinnamic acid. Then, the resultant crude crystals were recrystallized from dimethylformamide/water to give 4.67 g (yield 75%) of Compound 37 as a pale yellow powder.
