Synthesis of 1-(2,4-Dinitrophenyl)-3-methyl-4-substituted Heterocycles-2-pyrazolin-5-one

4-Bromo-1-(2,4-dinitrophenyl)-3-methyl-2-pyrazolin-5-one was reacted with the sodium salt of some reactive methylene compounds and then condensed with hydrazine hydrate, phenyl hydrazine, hydroxylamine hydrochloride, urea and thiourea to obtain the 4-subs
