N-(cyclohexylcarbamothioyl)benzamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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). at reflux temperature for 4 h The organic layer was concentrated to a small volume after which the product could be collected by filtration washed with petroleum ether dried in vacuo

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Benzoyl isothiocyanate (19.4 g, 118.9 mmol) was dissolved in dichloromethane and cooled to 0° C. Cyclohexylamine (13 g, 131.1 mmol) was added dropwise. Then the reaction was stirred at room temperature for 2 h. The mixture was washed with water, dried over sodium sulfate. Concentration under vaccum gave the title compound as a pale white solid in quantitative yield. The mixture was washed with water dried over sodium sulfate Concentration under vaccum
