Reference of 73112-16-0, 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 73112-16-0, name is 2,6-Dibromo-4-methylpyridine. This compound has unique chemical properties. The synthetic route is as follows.
Sodium tert-butoxide (0.15 g, 1.56 mmol) and l,l’-bis(di-tert- butylphsophino)ferrocene palladium dichloride (0.078 g, 0.12 mmol) were added to a mixture of 2,6-dibromo-4-methyl pyridine (0.301 g, 1.2 mmol) and tert-butyl carbamate (0.141 g, 1.2 mmol) in nitrogen sparged toluene (3 mL). The slurry was evacuated and refilled with nitrogen. After stirring at 60 C for 4 hours, the solution was cooled to 25 C, water (1 mL) was added and then the mixture extracted with ethyl actetate (2 x 50 mL), dried ( a2S04), filtered and concentrated in reduced pressure. The residue was chromatographed on silica gel to afford tert- butyl (6-bromo-4-methylpyridin-2-yl)carbamate as a white solid (0.3 g, 1.05 mmol). ‘H NMR (600 MHz, CDC13) delta 7.7 (s, 1H), 7.13 (s, 1H), 6.95 (s, 1H), 2.29 (s, 3H), 1.49 (s, 9H).
According to the analysis of related databases, 73112-16-0, the application of this compound in the production field has become more and more popular.
