Reaction Steps

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.
