Participants

Reaction Steps

To 5.2 ml (0.06 mole) chlorosulfonyl isocyanate in 75 ml dry xylenes was added 10.1 g (0.05 mole) of 2-(dimethylaminosulfamoyl)phenol in 15 ml xylenes, keeping the reaction temperature <5° C. This mixture was then heated to reflux temperature for 1 hour. The reaction solution was then cooled and the solvent evaporated to give an oil. The infrared spectrum showed NCO absorption at 2270 cm-1.
