Adding a certain compound to certain chemical reactions, such as: 5334-39-4, name is 3-Methyl-4-nitro-1H-pyrazole, 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 5334-39-4, Recommanded Product: 5334-39-4
Added 3-bromooxetane (451 ul, 5.901 mmol) to a mixture of 3-methyl-4-nitro-1 H-pyrazole (500 mg, 3.934 mmol) and cesium carbonate (2.564 g, 7.868 mmol) in DMF (5 mL) and stirred at 70 C for 6 d. Added ether (50ml_) and filtered off the residues. Removed the solvent from the filtrate in vacuo and purified the residue by flash chromatography using dichloromethane/ethyl acetate (3/7) to give the titled compound (589 mg, 82%). LCMS (Method 1 ) Rt 1.865 min.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3-Methyl-4-nitro-1H-pyrazole, other downstream synthetic routes, hurry up and to see.
