Abstract: Here we report the results of the study on the reaction of uric acid with benzylamine over sodium persulphate as the
oxidizer. The reaction is shown to furnish 4-benzylamino-5-benzylamino-allane-toine at a starting reagent molar ratio of 1:2, whereas
the 1:3 and 1:4 molar ratios afforded a mixture of 4-benzylamino-5-benzylamino-allantoine and 1-benzylamino-4-
benzylaminoallantoyne. The subsequent oxidation of 4-benzylamino-5-benzylamino-allantine with sodium persulphate over
ammonia yielded 4-benzylamino-allantoine; thus, the synthesis of this compound is through the two stages. In case benzylamine and
ammonia are injected immediately into the reaction with uric acid over the oxidizer, 4-benzylamino-allantoine is formed as well.
The results of this research are pretty interesting, and this research is to be continued.
Index terms: uric acid, 4-benzylamino-5-benzylamino-allantoine, sodium persulphate, benzylamine.
