Under a nitrogen atmosphere, a solution of N-cyclohexylsulfamic acid (50 g, 279 mmol) and PCl5 (58.1 g, 279 mmol) in 150 mL of toluene is very gently warmed up to 100° C. and maintained at that temperature for 1 hour. Distillation of the solution yields N-cyclohexylsulfamoyl chloride as a colorless solid (45.5 g, 82%).
