New downstream synthetic route of 13534-89-9

At the same time, in my other blogs, there are other synthetic methods of this type of compound,13534-89-9, 2,3-Dibromopyridine, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 13534-89-9, 2,3-Dibromopyridine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Formula: C5H3Br2N, blongs to pyridine-derivatives compound. Formula: C5H3Br2N

General procedure: 2,4-Dibromopyridine (0.236 g, 1 mmol) and phenol (0.094 g, 1 mmol), CuI (19.0 mg, 0.1 mmol), TMEDA (11.6 mg, 0.1 mmol), and cesium carbonate (0.65 g, 2 mmol) were placed in DMSO (5 mL). The reaction was stirred at 110 C under nitrogen atmosphere for 24 h. When the reaction mixture was cooled, the reaction mixture was filtered. The mixture was dissolved with dichloromethane (25 mL). Then the mixture was washed with brine (3×30 mL). The organic phase was dried over sodium sulfate. After evaporation of the solvent, the mixture was subjected to column chromatography with petroleum ether/ethyl acetate (20:1) as eluent to give pure product.
