Versuchsvorschrift

To a solution of N-(cyclohexylcarbamothioyl)benzamide (17.1 g, 65.5 mmol) in ethanol was added aqueous potassium carbonate (18.2 g, 132.2 mmol). The mixture was stirred at reflux temperature for 4 h. The organic layer was concentrated to a small volume, after which the product could be collected by filtration, then washed with petroleum ether and dried in vacuo to give the title compound as a white solid (9.8 g, 95% two steps).
