Extracurricular laboratory: Synthetic route of 56426-35-8

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.

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. 56426-35-8, name is Methyl 5-phenyl-1H-pyrazole-3-carboxylate, A new synthetic method of this compound is introduced below., name: Methyl 5-phenyl-1H-pyrazole-3-carboxylate

Intermediate 96 (320mg, 1.58mmol) was dissolved in THF/water (15mL, 1 :1), lithium hydroxide monohydrate (146mg, 3.48mmol) was added and the reaction mixture was stirred for 2h. The THF was removed in vacuo and the aqueous solution was acidified to pH 1 with 1M aq HCl. The precipitate was collected by filtration to give the title compound (232mg, 78%) as a yellow solid. LCMS: ES+ 189.0 [MH]+.
