In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 10250-64-3 as follows. Recommanded Product: 1-Methyl-3-phenyl-1H-pyrazole-5-carboxylic acid
General procedure: To a solution of 19 (1.2 eq) and HOBt(1.4 eq) in DMF (0.5 M) were added EDCI (1.3 eq) and a solution of 15a-j or 16a-j (1.0 eq) in DMF (0.25 M), Et3N (3.5 eq) at 0 C. The reaction mixture was stirred at room temperature for 24 hours, then diluted in AcOEt. The organic phase was washed with water twice, saturated aqueous NaHCO3 three times, and brine, then dried over Na2SO4,filtered, and concentrated. The residue was purified by flash column chromatography to give intermediates 17a-j and 18a-j.
According to the analysis of related databases, 10250-64-3, the application of this compound in the production field has become more and more popular.
