Application of 1015868-48-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1015868-48-0 name is 3-(4-Chlorophenyl)-1-methyl-1H-pyrazole-5-carboxylic acid, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: After hydrolysis of the ester, thionyl chloride (0.025mol) and catalytic amount of DMF were added to the solution of acid derivative (0.01mol) in CH2Cl2 under argon atmosphere and refluxed for 3h. Then, to the reaction mixture, diisopropylethylamine (0.015mol) and piperidine (0.01mol) were added and stirred overnight at room temperature. After the reaction was complete, the solvent was evaporated and the residue was purified by flash chromatography using CH2Cl2: MeOH solvent gradient.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 3-(4-Chlorophenyl)-1-methyl-1H-pyrazole-5-carboxylic acid, and friends who are interested can also refer to it.
