HCID 53790506HCID 53790506, compoundHCID 538674511-isopropyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde-(O-acetyloxime)HCID 54390112HCID 54390112, compound

Procedure

Following the same procedure and replacing 1-methyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehydeoxime by an equivalent of 1-ethyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehydeoxime, 1-isopropyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehydeoxime and 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxaldehydeoxime, respectively, results in the corresponding preparation of: 1-ethyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde-(O-acetyloxime), 1-isopropyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde-(O-acetyloxime), and 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxaldehyde-(O-acetyloxime), respectively.
