Synthetic Route of 72587-15-6, 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 72587-15-6, name is 2-Chloro-3-nitro-5-(trifluoromethyl)pyridine. This compound has unique chemical properties. The synthetic route is as follows.
Production Method of 2-Methyl-1-phenylpropan-2-yl 3-(3-ethylthio-5-trifluoromethylpyridin-2-yl)-2-(3-nitro-5-trifluoromethylpyridin-2-yl)-3-oxo-propionate Sodium hydride (240 mg, 3 Eq) was dissolved in DMA (dimethylacetamide) (2 mL). Under ice cooling, a DMA solution (2 mL) of 2-methyl-1-phenylpropan-2-yl 3-(3-ethylthio-5-trifluoromethylpyridin-2-yl)-3-oxo-propionate (895 mg, 2 mmol) was slowly added to the solution, and the mixture was stirred for 30 minutes. After that, a DMA solution (2 mL) of 2-chloro-3-nitro-5-trifluoromethylpyridine (454 mg, 1 Eq) was slowly added, and the mixture was stirred at room temperature for 4.5 hours. Water and 3 N hydrochloric acid were added to the reaction mixture, and ethyl acetate extraction was performed. The organic layer was concentrated and the residue was subjected to column chromatography to give the desired compound, i.e., 2-methyl-1-phenylpropan-2-yl 3-(3-ethylthio-5-trifluoromethylpyridin-2-yl)-2-(3-nitro-5-trifluoromethylpyridin-2-yl)-3-oxo-propionate (653 mg, containing about 20% nitropyridine (starting material)).
According to the analysis of related databases, 72587-15-6, the application of this compound in the production field has become more and more popular.
