Synthetic Route of 1070892-04-4, 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 1070892-04-4, name is 5-Bromo-2-(trifluoromethyl)isonicotinonitrile. This compound has unique chemical properties. The synthetic route is as follows.
To a mixture of delta-bromo^-trifluoromethyl-isonicotinonitrile 1-1 (2.51 g, 10 mmol) in dioxane (3.3 mL) and water (3.3 ml_), were added 2-chloro-4- methoxyphenylboronic acid (2.3 g, 12.5 mmol) and Na2CO3 (6.3 g). The mixture was purged with nitrogen gas for 10 min, then Pd(PPh3)4 (1.2 g, 1.0 mmol) was added. The mixture was stirred in a sealed vessel at 85 0C for 6 hrs, then extracted by ethyl acetate. The organic layer was washed with water, dried over MgSO4. Concentration and purification by silica gel column chromatography eluting with hexane/ethyl acetate (10/1 ) yielded 5-(2-chloro-4-methoxy-phenyl)-2-trifluoromethylisonicotinonitrile (1.31 g). tR = 2.96 min (method 1).
According to the analysis of related databases, 1070892-04-4, the application of this compound in the production field has become more and more popular.
