Versuchsvorschrift

29.5 parts of isopropylamine and 55.6 parts of triethylamine were introduced into 320 parts of THF. 60 parts of trimethylchlorosilane were added a little at a time at from 0° to -5° C. under nitrogen and the mixture was stirred at room temperature for 30 minutes and at 60° C. for 1 hour and then cooled to -10° C. 33.8 parts of sulfuryl chloride were added a little at a time and the mixture was allowed to warm to room temperature and was then stirred for 2 hours. The trimethylchlorosilane and the solvent were distilled off and the residue was washed with ice-water. 30.5 parts of N,N'-diisopropylsulfamide of melting point 98°-101° C. (starting substance) were obtained.
