Conditions

Temperature
60 °C

Procedure

A methylene chloride solution of N-trifluoroacetyl-4-(hexadecylamino)benzoyl chloride (4.8 g.) is added to a solution of 1.8 g. of sulfanilic acid in 1 N sodium hydroxide at 0° C. After 3 hours, the solution is warmed to 60° C. briefly and the whole evaporated to dryness. The residue is extracted with a small amount of cold water and the resulting white solid crystallized from aqueous ethanol.
