YieldReaction ConditionsOperation in experiment
75% EXAMPLE 3 1-Methyl-4-nitro-3-n-propylpyrazole-5-carboxylic acid 1-Methyl-3-n-propylpyrazole-5-carboxylic acid (12.1 g, 0.072 mol) was added portionwise to a mixture of oleum (13 ml) and fuming nitric acid (11 ml), keeping the temperature below 60° C. After the addition, the mixture was heated at 60° C. overnight and then cooled to room temperature before being poured onto ice. Filtration of the precipitate gave the nitropyrazole as a white solid (11.5 g, 75percent), m.p. 124°-127° C. Found: C,45.43; H,5.22; N,19.42. C8 H11 N3 O4 requires C,45.57; H,5.20; N,19.71percent.
