Paragraph 0079-0080, (2018/07/30)
The invention discloses a preparation method of methyl 2-nitryl-4-trifluoromethyl benzoate, belongs to the technical field of organic synthesis, and solves the technical problem that a new method forpreparing the methyl 2-nitryl-4-trifluoromethyl benzoate is provided. The method comprises the following steps: performing alkali catalytic or acid catalytic hydrolysis on 2-nitryl-4-trifluoromethyl benzonitrile to prepare 2-nitryl-4-trifluoromethyl phenyl methyl amide; mixing the 2-nitryl-4-trifluoromethyl phenyl methyl amide with a sulfuric acid-methanol solution and performing alcoholysis reaction to obtain the methyl 2-nitryl-4-trifluoromethyl benzoate. The method disclosed by the invention has the advantages of mild reaction conditions and simple post-processing; moreover, the high-puritymethyl 2-nitryl-4-trifluoromethyl benzoate can be obtained in a form of high yield, and realization of industrial production is facilitated.
