On December 31, 2017, Akbarzadeh, Marzieh; Bakavoli, Mehdi; Eshghi, Hossein; Shiri, Ali published an article.HPLC of Formula: 626-48-2 The title of the article was Synthesis of novel derivatives of (benz)imidazo[2,1-b]pyrimido[4,5-d][1,3]thiazine. And the article contained the following:
Several derivatives of the novel heterocyclic systems 2-substituted-imidazo- and benzimidazo-[2,1-b]pyrimido[4,5-d][1,3]thiazine were synthesized through the one-pot cyclocondensation of 2,4-dichloro-5-(chloromethyl)-6-methylpyrimidine with imidazolidine-2-thione and 1H-benzimidazole-2(3H)-thione and subsequently substituted by various secondary amines in moderately good yields. The experimental process involved the reaction of 6-Methylpyrimidine-2,4(1H,3H)-dione(cas: 626-48-2).HPLC of Formula: 626-48-2
