Versuchsvorschrift

To a solution of cyclohexylsulfamic acid (5 g, 27.9 mmol) in benzene (30 mL) was added dropwise phosphorus pentachloride (6.4 g, 30.7 mmol), and the mixture heated at reflux for 4 h. After the solvent was removed, the residue was distilled under reduced pressure to give the title compound (5 g, 91%).
