Reaction Steps

Stir together 2.5 g of 1-methyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehydeoxime, 1.27 g of acetic anhydride and 10 ml of benzene for 2 hours at from 80° to 85° C. Cool the resulting solution and vacuum filter to obtain 1-methyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde-(O-acetyloxime) [m.p. 192° to 197° C (with decomposition) from toluene] with a yield of 83%.
