Reaction Steps

To an ice-cold suspension of 14.7 g (0.1 mole) of phthalimide in 100 ml of 95% ethyl alcohol at 5° C., with stirring, 3.6 ml (0.11 mole) of 96.8% hydrazine was added dropwise. A slight exothermic reaction was observed and the mixture was allowed to stir at 5° C. for two hours. The mixture was diluted with 200 ml of ice water, stirred, filtered, washed with water and dried to give 12.2 g (75%) of white powder, m.p. 199°-202°.
