Procedure
Four gm. of methyl 1-(2-hydroxyethyl)-3-nitro-4-pyrazolecarboxylate was dissolved in a cold mixture of 25 ml. of absolute methanol and 25 ml. of condensed monomethylamine. The solution was allowed to stand in a stoppered container for 48 hours at room temperature. Evaporation of the volatile liquids under vacuum yielded a solid, which after decolorization and recrystallization from methanolisopropanol was proved to be 2.3 gm. of 1-(2-hydroxyethyl)-N-methyl-3-nitro-4-pyrazolecarboxamide, m.p. 138°-140° C.
