Adding a certain compound to certain chemical reactions, such as: 37718-11-9, name is 1H-Pyrazole-4-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 37718-11-9, Computed Properties of C4H4N2O2<\/a><\/p>\n

To the stirred solution of lH-pyrazole-4-carboxylic add 19-1 (20 g, 178.43 mmol) in methanol (100 niL) was added H2SO4 (17.50 g, 178.43 mmol, 9.51 rnL) at 0C and the reaction mixture was refluxed for 16 hours at 80C. Solvent was evaporated and the crude material was neutralized by saturated sodium bicarbonate solution. The aqueous layer was extracted with ethyl acetate and washed with brine. After separation, the organic layer was dried over sodium sulfate and evaporated to obtain methyl lH-pyrazole-4-earboxylate 19-2 (21 g, 166.52 mmol, 93.32% yield) as white solid. LC MS: ES+127.0.<\/p>\n
