Application of 129768-28-1, 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. 129768-28-1, name is 5-(Trifluoromethyl)-1H-pyrazole-3-carboxylic acid belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
A. Preparation ofN-( cis-4-fluoro-4-( 3-fluoro-5-( trifluoromethyl)phenylsulfonyl) cyclohexyl)-3 -(trifluoromethyl)- lH-pyrazole-5-carboxamide (200)[00296] Cis-4-fluoro-4-(3-fluoro-5-(trifluoromethyl)phenylsulfonyl)cyclohexanamine hydrochloride (124) (500 mg, 1.32 mmol), 3-trifluoromethyl-lH- pyrazole-5-carboxylic acid (199) (238 mg, 1.32 mmol), HATU (668 mg, 1.8 mmol), and TEA (740 mu, 5.3 mmol) were stirred in DCM (15 mL) at room temperature for 16 hours. The reaction was diluted with DCM, washed sequentially with NH4C1 saturated solution and Na2HC03 saturated solution, dried (Na2S04), and concentrated in vacuo. The residue purified by automated flash chromatography (20% EtOAc/PE) to give N-(cis-4-fluoro-4-(3-fluoro-5-(trifluoromethyl)phenylsulfonyl) cyclohexyl)-3- (trifluoromethyl)-lH-pyrazole-5-carboxamide (200) (530 mg, 82%).
The synthetic route of 5-(Trifluoromethyl)-1H-pyrazole-3-carboxylic acid has been constantly updated, and we look forward to future research findings.
