Application of 20970-75-6, 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 20970-75-6, name is 2-Cyano-3-methylpyridine. This compound has unique chemical properties. The synthetic route is as follows.
To a 500 mL single-neck round bottom flash fitted with a reflux condenser and a nitrogen outlet was added 10.1 g (86 mmol) 3-methylpicolinonitrile, 200 mL dimethyl carbonate, 18.2 g (103 mmol) N-bromosuccinimide and 2.1 g (8.5 mmol) benzoyl peroxide. The resulting reaction mixture was heated to 87 C and stirred for 5 h. Following this duration, the reaction mixture was cooled to ambient temperature and filtered, and the solid was rinsed with Et20. DCM was subsequently added to the filtrate and the resulting mixture was filtered. The combined organics were concentrated and the resulting semi-solid was purified by silica gel chromatography (2 x 330 g column, 5-35% EtOAc/Hexane) followed by reverse-phase HPLC (Waters Xbridge Prep C18 10 muetatauiota OBD, 50 x 250 mm column) to afford the title compound as a yellow solid (6.3 g, 32.0 mmol, 37% yield). LC-MS m/z 196.8 (M+H)+, 0.60 min (ret. time).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 20970-75-6, 2-Cyano-3-methylpyridine.
