실험 절차

At from 23° to 30° C add a warm solution of 7.5 g of 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxylic acid chloride in 200 ml of acetone and 250 ml of dioxane dropwise to a solution of 1.84 g of sodium azide in 24 ml of water. Stir the resulting reaction mixture for a further 15 minutes and then dilute it with 600 ml of water cooling with ice to obtain a 98% yield of 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxylic acid azide [m.p. 134° C (with decomposition)].
