Electric Literature of 155377-19-8<\/a>, These common heterocyclic compound, 155377-19-8, name is Ethyl 3-(trifluoromethyl)pyrazole-4-carboxylate, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.<\/p>\n

Reference Example 11 Ethyl 3-trifluoromethylpyrazole-4-carboxylate (5 g), potassium carbonate (3.48 g) and ethyl iodide (2.3 ml) in acetonitrile were heated at reflux overnight. After cooling, ethyl acetate and water were added and the organic phase separated. The aqueous layer was extracted with ethyl acetate and the combined organic extracts were dried (magnesium sulphate) and evaporated under reduced pressure to give a yellow oil which was purified by crystallisation in hexane to produce 4-ethoxycarbonyl-1-ethyl-3-trifluoromethylpyrazole as white crystals (3.65 g), 1 H NMR (CDCl3) delta1.25(3H,t), 1.45(3H,t), 4.10(2H,q), 4.20(2H,q) 7.90(1H,s) ppm.<\/p>\n

The synthetic route of 155377-19-8 has been constantly updated, and we look forward to future research findings.<\/p>\n
