Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2075-46-9, name is 4-Nitro-1H-pyrazole, A new synthetic method of this compound is introduced below., Quality Control of 4-Nitro-1H-pyrazole<\/a><\/p>\n

4-Nitro-1H-pyrazole (1.13 g, 9.99 mmol) was dissolved in 15 mL of dry THF.The reaction flask was placed in an ice bath and cooled, and NaH (600 mg, 25 mmol) was slowly added.Stir to room temperature and stir for 2.5 h, then slowly add methyl iodide (3.84 g, 20 mmol).Stirring was continued for 1.5 h, and the reaction was quenched by slowly adding 15 mL of saturated brine.The reaction solution was concentrated under reduced pressure and ethyl acetate (50 mL\u00a1\u00c13)Wash with water, saturated brine (50 mL\u00a1\u00c12), dry over anhydrous sodium sulfate,1-Methyl-4-nitro-1H-pyrazole (826 mg, 65%) was obtained as a pale yellow solid.<\/p>\n
