Versuchsvorschrift

A mixture of 2-nitrophenylhydrazine (2.00 g), hexane-3,4-dione (1.80 g), sulfuric acid (2 drops) and ethanol (20 mL) was heated under reflux for 1 hr. The reaction mixture was poured into water, and the resulting crystals were collected by filtration, washed with water and dried to give the title compound (3.13 g, 96%) as brown crystals. melting point 96-97° C.
