Reaction Steps
2,5-Dichlorophenylhydrazine hydrochloride (240 g, 1.1 mol) and acrylamide (100 g, 1.4 mol) is refluxed in a solution of sodium (56 g, 2.4 mol) in ethanol (1000 ml) and toluene (1000 ml) for 3 hours. Evaporation of the solvents, acidification with acetic acid dilution with water, filtration and drying (high vacuum, +100° C.) gives the 1-(2,5-dichlorophenyl)-3-pyrazolidone.
