Adding a certain compound to certain chemical reactions, such as: 98273-79-1, Methyl 3-chloroisonicotinate, 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, category: pyridine-derivatives, blongs to pyridine-derivatives compound. category: pyridine-derivatives
To a solution of 3-chloro-pyridine-4-carboxylic acid methyl ester (0.28 g, 1.65 mmol) in DMF (10 ml) are added cesium carbonate (2.68 g, 8.25 mmol) and 3,3-difluoro-3-(4-fluorophenyl)-propane-1 -thiol (synthesized according to the methods described in sections a) and b) of example 3) (0.34 g, 1.65 mmol) in a sealed tube. The reaction mixture is stirred at 90C for 1 h. After completion of the reaction, the mixture is diluted with water (15 ml) and extracted with EtOAc (3 x 20 ml). The organic layer is washed with water (20 ml), brine (20 ml), dried over anhydrous sodium sulfate and evaporated to get the crude product, which is purified by column chromatography (silica gel, 10% acetone/hexane) to yield 3-[[3,3- difluoro-3-(4-fluorophenyl)-propyl]sulfanyl]-pyridine-4-carboxylic acid methyl ester (0.19 g, 0.56 mmol, 34%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,98273-79-1, Methyl 3-chloroisonicotinate, and friends who are interested can also refer to it.
