Synthetic Route of 92534-69-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 92534-69-5 as follows.

A mixture of 2-methyl-4-nitro-2H-pyrazole-3-carboxylic acid (138.8 mmol) and thionyl chloride (300 mL) is heated under reflux for 12 h. The mixture is then concentrated to dryness under reduced pressure. The resulting oil is dissolved in acetone (200 mL) and it is added to cold aqueous ammonium hydroxide with stirring. The precipitate is collected by filtration and it is dried to give 2- methyl-4-nitro-2H-pyrazole-3-carboxylic acid amide as an off-white solid. Compound wt: 10.5g, 45% yield.[00253] 1H NMR (400 MHz, DMSO-^6) delta: 8.47 (IH, s); 8.32 (IH, s); 8.27 (IH, s); 3.86 (3H, s).
