Versuchsvorschrift

The 2-(methylthio)phenyl hydrazine (5.32 g, 30.0 mmol) and 4-piperidone (4.07 g, 30.0 mmol) were partially dissolved in the ethanol (75 mL) and heated initially to reflux for 1 h. A heavy precipitate formed from the almost clear solution. The reaction was then treated with the conc hydrochloric acid (2.5 mL) and diluted with further ethanol (25 mL) to assist stirring and heating continued for a further 4 h. After cooling to RT overnight the solid was filtered washing isopropanol (25 mL). Obtained 7.70 g
