Procedure

A 4 g. sample of ethyl 4-(14-methylpentadecyl)aminobenzoate is hydrolized with 2.0 g. of 85% potassium hydroxide in 60 ml. 95% ethanol by refluxing the solution for 5 hours. The solution is cooled, diluted with 100 ml. water, and acidified to pH 4.5 with 37% hydrochloric acid. The precipitate is collected and dried in vacuo to yield the title compound as a white powder.
