Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 141573-95-7, name is Ethyl 3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylate, A new synthetic method of this compound is introduced below., Recommanded Product: 141573-95-7<\/a><\/p>\n

In a 100 mL reaction flask, add ethyl 1-methyl-3-difluoromethyl-1H-pyrazole-4-carboxylate(38 mmol) represented by formula (II), and then add 10% by mass 30mL NaOH aqueous solution, heated to 60 C and stirred until the reaction solution was transparent, and then naturally cooled to room temperature. The reaction solution was adjusted to pH about 2.0 by adding acid, a large amount of solid was precipitated, filtered by suction, and the filter residue was washed with water and dried to obtain the formula 1) -methyl-3-difluoromethyl-1H-pyrazole-4-carboxylic acid.<\/p>\n

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.<\/p>\n
