반응 단계
Add a solution of 1.0 g of 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxylic acid chloride in 50 ml of pyridine dropwise to a solution of 0.31 ml of phenyl hydrazine in 5 ml of pyridine and stir the resulting reaction mixture at room temperature for 4 hours. Pour the thus-produced solution onto ice and water and chromatograph on silica gel with benzene/ethanol (9:1) to obtain 3-(5-nitro-2-furyl)-1,N'-diphenylpyrazole-4-carbohydrazide.
