Introduction of a new synthetic route about Methyl 5-bromo-4-methylpicolinate

With the rapid development of chemical substances, we look forward to future research findings about 886365-06-6.

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 886365-06-6, name is Methyl 5-bromo-4-methylpicolinate. This compound has unique chemical properties. The synthetic route is as follows. category: pyridine-derivatives

1-116: 5-Bromo-4-methyl-pyridine-2-carboxylic acid methyl ester (800 mg, 3.48 mmol) was dissolved in DMF (16 mL). Tetrakis(triphenylphosphine)palladium(0) (462 mg, 0.400 mmol), potassium carbonate (2.07 g, 15.0 mmol), and 2,2-dimethylethenylboronic acid pinacol ester (0.82 mL, 4.0 mmol) were added. Argon was bubbled through the mixture for 5 min. The mixture was heated to 120C in a microwave reactor for 1 h. The mixture was diluted with sat’d ammonium chloride (10 mL) then extracted with EtOAc (3×5 mL). The combined organics were dried over sodium sulfate and concentrated. The resulting crude material was purified by silica gel chromatagraphy using 0-40% EtOAc in heptanes as the gradient to provide compound 1-116.

With the rapid development of chemical substances, we look forward to future research findings about 886365-06-6.
