Reaction Steps
Heat 2.0 g of 1-methyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde together with 2.5 g of 3-hydrazinoquinoline dihydrochloride and 1.8 g of anhydrous sodium acetate in 40 ml of ethanol for 3 hours at boiling point and then allow the resulting admixture to stand overnight. Separate the formed precipitate by filtration and stir it up with a little water to obtain an 86% yield of 1-methyl-3-(5-nitro-2-furyl)pyrazole-4-carboxaldehyde-3-quinolylhydrazone [m.p. 236° to 238° C (with decomposition)].
