Procedure

Chlorosulfonyl isocyanate (2.43 g) was dissolved in diethyl ether (10 mL), and at −15° C., the solution was added dropwise to a solution of 2,6-diisopropylaniline in diethyl ether (15 mL). After the mixture was stirred at the same temperature for 1 hour and 30 minutes, the resulting precipitates were collected by filtration and then washed with hexane. Colorless crystals so obtained were dried to afford [[[(2,6-diisopropylphenyl)amino]-carbonyl]amino]sulfonyl chloride (4.11 g). Yield: 75%.
