Procedure

A solution of 21.1 g. of 4-(hexadecylamino)benzoyl chloride hydrochloride and 10.8 g. of p-tert-butylbenzenesulfonamide in 250 ml. of pyridine was stirred under reflux for 2 hours and evaporated. The residue was partitioned between 1N hydrochloric acid and CH2Cl2 and the organic layer was separated, washed with water, dried (MgSO4), and evaporated. Crystallization of the residual glass from CH2Cl2 hexane afforded a white solid, melting point 173°-176° C.
