Reaction Steps
In a round bottom flask containing a solution of phosgene (1.573 mL) in dichloromethane (5 mL) was added 4-amino-3-chlorobenzenesulfonamide (0.206 g) and N-ethyl-N-isopropylpropan-2-amine (0.521 mL). The resulting clear solution was stirred at room temperature overnight. The mixture was concentrated and further dried under vacuum to provide the title compound.
