A Facile Microwave-Assisted “One-Pot” Synthesis of Piperazino Pyrimidinyl Acetamides, a Class of Hybrid Bis Heterocycles and Their Structural Elucidation Using NMR Spectral Techniques was written by Kanagarajan, V.;How, Ghee Ang;Siu, Choon Ng;Gopalakrishnan, M.. And the article was included in Journal of Heterocyclic Chemistry in 2013.Safety of 4,6-Diphenylpyrimidin-2-amine This article mentions the following:
An array of novel piperazino pyrimidinyl acetamides, a class of hybrid bis heterocycles are synthesized in “one-pot” by microwave irradiation method catalyzed by heterogeneous NaHSO4.SiO2 catalyst in dry media and are characterized by m.p., elemental anal., MS, FT-IR, one-dimensional NMR (1H and 13C) and two-dimensional 1H-1H COSY and 1H-13C HSQC spectral data. In the experiment, the researchers used many compounds, for example, 4,6-Diphenylpyrimidin-2-amine (cas: 40230-24-8Safety of 4,6-Diphenylpyrimidin-2-amine).
4,6-Diphenylpyrimidin-2-amine (cas: 40230-24-8) belongs to pyrimidine derivatives. Pyrimidine also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. A Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones enables an efficient and facile synthesis of structurally important pyrimidines via a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization.Safety of 4,6-Diphenylpyrimidin-2-amine
