Stir 4.14 g of 3-(5-nitro-2-furyl)-1H-pyrazole-4-carboxaldehyde together with 2.0 g. of thiosemicarbazide, 2 drops of glacial acetic acid and 40 ml of ethanol for 2 hours at 50° C and then for 4 days at room temperature. Dilute the resulting product with water to produce a 95% yield of 3-(5-nitro-2-furyl)-1H-pyrazole-4-carboxaldehyde-thiosemicarbazone [m.p. above 350° C (with decomposition)].
