Procedure

A solution of 5 g. of ethyl 4-(13,13-dimethyltetradecyl)aminobenzoate in 75 ml. 95% ethanol is saponified with 2.5 g. of 85% potassium hydroxide by refluxing for 5 hours. The warm solution is diluted with 150 ml. water and adjusted to pH 5 with 37% hydrochloric acid. The precipitate is filtered, washed with water, dried in vacuo and crystallized from acetic acid to yield the title compound as a cream-colored, amorphous solid.
