Versuchsvorschrift
The reactant N-chloroacetyl 4-chlorobenzene sulfonamide was prepared by mixing 30.0 g of 4-chlorobenzene sulfonamide and 60.0 ml of chloroacetylchloride. The mixture was refluxed for 6 hours, allowed to cool, and stand at room temperature overnight. The crystalline product was removed by filtration, washed repeatedly with hexane, and dried. The product consisted of 32.5 g of reactant (m.p. 122°-124° C.). Structure was confirmed by IR and NMR.
