The author of 《Early Process Development of an Irreversible Epidermal Growth Factor Receptor (EGFR) T790 M Inhibitor》 were Tao, Yong; Keene, Nandell F.; Wiglesworth, Kristin E.; Sitter, Barbara; McWilliams, J. Christopher. And the article was published in Organic Process Research & Development in 2019. Electric Literature of C6H3Cl2N3 The author mentioned the following in the article:
The original synthesis of the irreversible epidermal growth factor receptor (EGFR) T790 M inhibitor 1 (I) was enabled by successful application of ammonium hydroxide to cleanly cleave the N-hydroxymethyl group and by development of high yielding conditions for the subsequent amidation reaction. Furthermore, a protection-free and regioselective new synthetic route was developed that shortened the synthesis from the original 8 steps to 6 steps and improved the overall yield from 5% to 34% on scale. Crystallizations of 1 and intermediates were correspondingly developed to control the quality en route. After reading the article, we found that the author used 2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine(cas: 90213-66-4Electric Literature of C6H3Cl2N3)
2,4-Dichloro-7H-pyrrolo[2,3-d]pyrimidine(cas: 90213-66-4) belongs to pyrimidine. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own. Electric Literature of C6H3Cl2N3They have been used in a wide variety of pharmaceuticals including general anesthetics, anti-epilepsy medication, anti-malaria medication, drugs for treating high blood pressure, and HIV medication.
