A mixture of 7.0 g of ethyl p-[(11-phenoxyundecyl)amino]benzoate, 7.0 g of potassium hydroxide and 150 ml of ethanol-water (9:1) is refluxed for 3.5 hours. The mixture is made acidic while hot with concentrated hydrochloric acid, diluted with water, cooled and filtered to give white crystals, mp 117°-119° C. Recrystallization from ethanol gives white crystals, mp 118°-119.5° C.
