Reaction Steps
In the manner described in IV above, 16.9 gm (0.13 mol) of 6-methyl-5,6-dihydrouracil were reacted with ketene in boiling ethyl acetate in the presence of sodium acetate. The product was recrystallized from a mixture of benzine (b.p. 70° C. to 95° C.) and isopropanol in the volume ratio of 1:1. The melting point was 84° C. to 86° C., and the elementary analysis resulted in the following values:
