Related Products of 5334-39-4<\/a>, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 5334-39-4, name is 3-Methyl-4-nitro-1H-pyrazole belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.<\/p>\n

To a stirred solution of PPh3 (4.28 g, 0.016 mole, 1.1 equiv) and DIAD (3.33 gm,, 0.016 mole, 1.1 equiv) in THF (2mL), was added 4-nitro-lH-pyrazole (1.96 g, 0.004 mmol, 1.0 equiv) The reaction mixture was added l-[2, 4-bis (trifluoromethyl) phenyl] ethanol (4 g, 0.004 mmol, 1.0 equiv). The reaction mixture was stirred at room temperature for 1 hrs. Product formation was confirmed with TLC and LCMS. After completion of reaction mixture were diluted with EtOAc (50 mL) and washed with water (3×50 mL). Organic layer dried over anhydrous Na2S04 and concentrated under reduced pressure to obtain crude which was further purified by flash column chromatography to obtain pure product l-(l-(2,4- bis(trifluoromethyl)phenyl)ethyl)-5-methyl-4-nitro-lH-pyrazole (0.5 gm) and l-(l-(2,4- bis(trifluoromethyl)phenyl)ethyl)-3-methyl-4-nitro-lH-pyrazole (1.5 gm). LCMS: 368 [M+H] +.<\/p>\n

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.<\/p>\n
