52867-42-2, A common compound: 52867-42-2, name is Methyl 2-methyl-5-oxo-2,5-dihydro-1H-pyrazole-3-carboxylate, belongs to pyrazoles-derivatives compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below.
In a three-necked round bottom flask were successively added acetone 20mL, methyl 3-hydroxy-1-methylpyrazole-5-carboxylate 5mmol, 1,1,3_ trichloropropene 5.5mmol alkaline conditions at room temperature for 12h, filtered , Acetone, and concentrated to give methyl 3- (3,3-dichloroallyloxy) -1-methylpyrazole-5-carboxylate as a white solid in 95% yield, purity 95%
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, Methyl 2-methyl-5-oxo-2,5-dihydro-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.
