Cyclohexylamine → N-cyclohexyl-4-(4-nitrophenoxy)benzenesulfonamide

Participants

Reaction Steps

4-(4-Nitrophenoxy)benzenesulphonyl chloride (Example 1) (18.8 g), cyclohexylamine (6.5 g), anhydrous potassium carbonate (8.3 g) and acetone (100 ml) were refluxed together for 4 hours. On concentration and addition of water, an oil separated which solidified overnight. From ethanol on addition of light petroleum (b.p. 60°-80° C.), 4-(4-nitrophenoxy)-N-cyclohexylbenzenesulphonamide was obtained in the form of crystals, m.p. 94° C.
