In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 886365-06-6, name is Methyl 5-bromo-4-methylpicolinate, the common compound, a new synthetic route is introduced below. Formula: C8H8BrNO2
(2-Fluoro-4-methoxyphenyl)boronic acid (177 mg, 1.043 mmol), methyl 5-bromo-4- methylpyridine-2-carboxylate (200 mg, 0.869 mmol), 1,3 bis(di-tert-butylphosphino)ferrocene palladium dichloride (89 mg, 0.130 mmol), cesium carbonate (623 mg, 1.913 mmol) and THF (5 mL) were sealed in a microwave vessel and subject to microwave irradiation at 140 C for 20 min. The reaction crude was combined with the crude from an identical probe reaction (44.3 mg scale). Volatiles were removed under reduced pressure. The resulting pot residue was purified by preparative HPLC (reverse phase, Kromasil 100-5C18, 100×21.1 mm) eluting with acetonitrile/water + 0.1% TFA (30% to 100% organic in 10 min, then to 100% for 2 min, 20 mL/min). Related fractions were pooled and evaporated under reduced pressure to afford a dark solid. This solid was further purified by flash chromatography (Si02, Biotage SNAP Cartridge, silica gel, KP-Sil, 50 g cartridge). The column was eluted with an EtOAc hexanes mixture (0% to 100%). Related fractions were pooled and evaporated to afford a light yellow oil as the titled compound. LCMS calc. = 275.10; found = 276.11 (M+H)+.
The synthetic route of 886365-06-6 has been constantly updated, and we look forward to future research findings.
