Versuchsvorschrift

To a stirred solution of (E)-3-(dimethylamino)-1-phenylprop-2-en-1-one (2.63 g, 15 mmol) in ethanol (40 ml) was added hydrazine hydrate (1.459 ml, 30.0 mmol). The reaction was heated to 100° C. for 2 hours. Whereupon was cooled to room temperature and ethanol was removed by vacuum. The residue was partitioned between DCM and water. The organic phase was dried over MgSO4 and filtered. After evaporation the crude product was purified by triturating with a mixture of petroleumether and ethyl acetate. (Yield: 1.59 g, 73%).
