4-アミノウラシルのメチル化に就いて その2

抄録

In the formation of 3-methyl-4-aminouracil (II) from 4-aminouracil (I), the relationship between the methylation agent, pH, amount of sodium hydroxide, and the reaction temperature was examined and the maximum yield of 65% was obtained. The structure of 4-aminouracil was examined from its chemical reactions and the spectrum and equilibrium formulae by the change of pH were forwarded. The perchlorate of allied substances were prepared for comparative identification and detection.
