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. 181585-93-3, name is Methyl 5-nitro-1H-pyrazole-3-carboxylate, A new synthetic method of this compound is introduced below., SDS of cas: 181585-93-3<\/a><\/p>\n

Step 12: Preparati -Methyl-5-nitro-2H-pyrazole-3-carboxylic acid methyl ester A 100-mL single-neck round-bottomed flask was charged with methyl 5-nitro-lH-pyrazole-3- carboxylate (3.89 g, 22.7 mmol), anhydrous DMF (30 ml) , potassium carbonate (6.28 g, 45.5 mmol). Mel (4.19 g, 1.85 ml, 29.6 mmol) was added and the reaction mixture was stirred at room temperature for 18h. The mixture was then diluted with water (150 mL) and extracted with DCM (3 x 75mL). The combined organic layers were dried over MgS04 and concentrated under vacuum. The crude material was purified by flash chromatography (silica gel, AnaLogix system, SF40-240g column, 10% to 50% EtOAc in hexanes) to give the desired product as mixture of isomers (3.75 g). M+ = 185.0 m\/e<\/p>\n
