Versuchsvorschrift

A solution of 5.4 g. of methyl 3-[4-[14-(trimethylsilyl)tetradecylamino]benzoyl]propionate is stirred with 5.4 g. of potassium hydroxide in 100 ml. of 95% ethanol for 3 hours at reflux. The reaction mixture is cooled, diluted with 50 ml. of ethanol and 100 ml. of water, and neutralized with hydrochloric acid. The solution is cooled to room temperature and filtered. The white solid is washed with 50% aqueous ethanol and dried. The product is recrystallized to yield 3-[4-[14-(trimethylsilyl)tetradecylamino]benzoyl]propionic acid as a white crystalline solid.
