1-hydroxyethyl-4-nitropyrazole Chemical Properties,Usage,Production

Synthesis

2075-46-9

540-51-2

42027-81-6

GENERAL STEPS: A mixture of 2-bromoethanol (3.75 g, 30.00 mmol), 4-nitropyrazole (3.39 g, 30.00 mmol) and potassium carbonate (K2CO3, 4.97 g, 36.00 mmol) in acetonitrile (30 mL) was heated and refluxed for 16 hours. Upon completion of the reaction, the mixture was filtered and the filtrate was concentrated under reduced pressure to remove the solvent to afford the crude product 1-(2-hydroxyethyl)-4-nitro-1H-pyrazole as a white solid (4.70 g, yield: 100%), which could be used in the next reaction without further purification. The product was analyzed by electrospray ionization mass spectrometry (ESI-MS) and showed a molecular ion peak (M + H)+ m/z of 158.0.
