Application of 10250-63-2, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 10250-63-2, name is Ethyl 1-methyl-3-phenyl-1H-pyrazole-5-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
Production Example 197c) 0.12 g of ethyl 1-methyl-3-phenyl-1H-5-pyrazolecarboxylate was dissolved in 5 ml ethanol. 1 ml of 5N aqueous sodium hydroxide solution was added thereto, followed by heating under reflux for 1 hour. The reaction solution was ice-cooled, neutralized with 2N hydrochloric acid and then extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and evaporated, to give 0.11 g of 1-methyl-3-phenyl-1H-5-pyrazolecarboxylic acid. 1H-NMR(CDCl3) delta: 4.22(s, 3H) 7.22(s, 1H) 7.33(t, J=8.0Hz, 1H) 7.40(t, J=8.0Hz, 2H) 8.80(d, J=8.0Hz, 2H)
The synthetic route of Ethyl 1-methyl-3-phenyl-1H-pyrazole-5-carboxylate has been constantly updated, and we look forward to future research findings.
