Reaction Steps

A solution of 8.8 g. of ethyl 4-(15-carbomethoxypentadecylamino)benzoate, 4.5 g. of potassium hydroxide, and 10 ml. of water in 90 ml. of ethanol is stirred at 75° for 10 hours, cooled, diluted with water, brought to pH 4 with dilute hydrochloric acid, and filtered. The solid is dried and crystallized from acetic acid to yield 4-(15-carboxypentadecylamino)benzoic acid as a white crystalline solid.
