Procedure

A solution of 5 g. of ethyl 4-(15-carbomethoxypentadecylamino)benzoate and 0.8 g. of potassium hydroxide in 50 ml. of 95% ethanol is stirred at 50° C. for 10 hours, diluted with 100 ml. of water and acidified with concentrated hydrochloric acid. The solid is collected by filtration, dried, and recrystallized from toluene to yield ethyl 4-(15-carboxypentadecylamino)benzoate as a white solid.
