On May 31, 2015, Dubovitskii, S. N.; Komissarova, N. G.; Shitikova, O. V.; Spirikhin, L. V.; Abdullin, M. F.; Yunusov, M. S. published an article.Computed Properties of 626-48-2 The title of the article was Synthesis of Betulin 28-(2-Bromoacetate) Conjugates with Uracil and its Methyl-Substituted Homologs. And the article contained the following:

A series of potentially biol. active betulin derivatives containing various C-28 2-uracilacetoxy substituents were synthesized [e.g., betulin bromoester I + uracil → II (88%)]. The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).Computed Properties of 626-48-2
