実験手順
Fifty ml. of water was cooled in an ice bath and saturated with monomethylamine. To the solution was added 2 gm. of 1-methyl-3-nitro-4-pyrazolecarbonyl chloride in portions, and the mixture was heated until the solid dissolved. Upon cooling a solid precipitated which was recrystallized from water and identified as 1.3 gm. of N,1-dimethyl-3-nitro-4-pyrazolecarboxamide, m.p. 163°-165° C.
