Reaction Steps
Add 2.0 g of [3-(5-nitro-2-furyl)-1-phenylpyrazol-4-ylmethylene]dimethylammonium perchlorate, 0.4 g. of anhydrous sodium acetate and 0.63 g of ethyl carbazate to 10.5 ml of dimethylformamide. Stir the resulting admixture for 30 minutes before adding 30 ml of water dropwise thereto to obtain a 95% yield of 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxaldehyde-ethoxycarbonylhydrazone [m.p. 200° to 201° C].
