실험 절차

15 parts of dichloromethylenedimethylammonium chloride, suspended in 540 parts of 1,2-dichloroethane, are saturated with 40 parts of phosgene at 35° C, whilst stirring. 89.6 parts of cyclohexylsulfamic acid are now added and a further 550 parts of phosgene are then introduced in the course of 15 hours at 83° C, whilst stirring. After removing excess phosgene, and the solvent, under reduced pressure, 67.2 parts (68% of theory) of cyclohexylsulfamic acid chloride of boiling point 100°-114° C/0.01 mm Hg and melting point 43°-47° C are obtained by distillation of the residue.
