In 2018,Medicinal Chemistry (Sharjah, United Arab Emirates) included an article by Trifonov, Lena; Afri, Michal; Palczewski, Krzysztof; Korshin, Edward E.; Gruzman, Arie. COA of Formula: C8H6FNO4. The article was titled 《An Expedient Synthesis of CMF-019: (S)-5-Methyl-3-{1-(pentan-3-yl)-2-(thiophen-2-ylmethyl)-1H-benzo[d]imidazole-5-carboxamido}hexanoic Acid, a Potent Apelin Receptor (APJ) Agonist》. The information in the text is summarized as follows:
Here, a detailed preparation of (S)-5-methyl-3-{1-(pentan-3-yl)-2-(thiophen-2-ylmethyl)-1H-benzo[d]imidazole-5-carboxamido}hexanoic acid (CMF-019) (I) through a modified and improved synthetic pathway was described. The results came from multiple reactions, including the reaction of Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9COA of Formula: C8H6FNO4)
Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9) belongs to methyl benzoate. Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.COA of Formula: C8H6FNO4
