Adding a certain compound to certain chemical reactions, such as: 25016-20-0, name is 1-Methyl-1H-pyrazole-3-carboxylic acid, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 25016-20-0, Product Details of 25016-20-0
1-methyl-1H-pyrazole-5-carboxylic acid (35 mg, 0.28 mmol, 1.1 equiv.), HATU (109 mg, 0.29 mmol,1.15equiv.), DIPEA (37mg, 0.29mmol, 1.15equiv.) is dissolved in an appropriate amount of DMF, stirred for 10 minutes and then added (4-fluoro-2-(Trifluoromethyl)phenyl)(5-aminoindolin-1-yl)methanone (81 mg, 0.25 mmol, 1.0 equiv.), stirring at room temperature for 8 hoursTime. The TLC monitors the reaction in real time. After the reaction, dilute with water, extract the appropriate amount of ethyl acetate three times, combine the organic phase, and then use water,The mixture was washed with saturated NaHCO3 solution and saturated NaCl solution, and the organic layer was dried over anhydrous NaSO?Purification afforded N-(1-(4-fluoro-2-(trifluoromethyl)benzoyl)indolin-5-yl)-1-methyl-1H-pyrazole-3-carboxamide(80 mg, yield: 74%).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1-Methyl-1H-pyrazole-3-carboxylic acid, and friends who are interested can also refer to it.
