実験手順
Add 1.06 ml. of pyrrolidine in 2 ml of dioxane dropwise to 1.0 g of 3-(5-nitro-2-furyl)-1-phenylpyrazole-4-carboxylic acid chloride in 43 ml of dioxane at 35° C under stirring. Stir the resulting solution for an hour at room temperature and then concentrate it. Wash the resulting precipitate with water to obtain a 99% yield of 1-[3-(5-nitro-2-furyl)-1-phenyl-4-pyrazolylcarbonyl]pyrrolidine [m.p. 236.5° to 237.5° C].
