Synthetic Route of 52718-95-3, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 52718-95-3, name is Methyl 2-bromonicotinate. This compound has unique chemical properties. The synthetic route is as follows.
Part D. Preparation of methyl 2-(3′-cyanophenyl)nicotinate. Methyl 2-bromonicotinate (2.0 g, 9.3 mmol) and 3-cyanophenylboronic acid (2.7 g, 18.4 mmol) were combined in 190 mL benzene. Sodium carbonate (19 mL of a 2 M aqueous solution), tetrabutylammonium bromide (152 mg, 0.5 mmol), and bis(triphenylphosphine)palladium(II) chloride (325 mg, 0.5 mmol) were added. The entire mixture was evacuated to remove dissolved gasses, then placed under argon. The reaction was refluxed for 14 hours, diluted with water and EtOAc, separated, dried over Na2 SO4, filtered, and evaporated. The resulting yellow solid was chromatographed on silica gel (30% EtOAc/hexanes) to yield a light yellow solid (1.70 g, 77%). 1 H NMR (CDCl3): delta 8.81 (dd, 1H, J=4.8, J’=1.8), 8.23 (dd, 1H, J=8.0, J’=1.9), 7.85 (s, 1H), 7.73 (m, 2H), 7.55 (t, 1H, J=7.7), 7.43 (m, 1H), 3.76 (s, 3H).
According to the analysis of related databases, 52718-95-3, the application of this compound in the production field has become more and more popular.
